Ode on Melancholy Essay Example

Ode on Melancholy Paper Keats gains inspiration from many sources, the most important of which is the natural world. Explore the varied poetic uses Keats makes of nature in the Ode on Melancholy and Ode to Autumn Keats refers to nature in many of his poems. The natural world and the human world are inspiring to him and he portrays both these ideas in the poem Ode on Melancholy. He describes nature and its beauty through descriptive language in this ode. In this ode nature present the joys in life as well its melancholic ways. Keats uses themes of mutability, nature and its course and synaesthesia. These inspirations Keats uses enable him to be a universally renowned poet as the themes give his poems individuality. Keats wrote during the Romantic period and observations and description of the natural world were very typical of writers in the period. Nature is shown in several forms throughout Ode on Melancholy and Ode to Autumn as Keats learns to accept the truth of life and all of its qualities and nature helps discover and highlight this. Ode to Melancholy begins with the descriptions of nature through the idea of suffering. Negative images are displayed, No, no telling you not to reject melancholy but learn to accept it. Poisonous plants are mentioned showing the idea of suicide, wolfs-bane and its poisonous wine suggests death and sickness through imagery of colour and the idea of pain. The first stanza urges you not to try and escape pain but to learn from it. Poison is referred to again in the final stanza in order to show Keats connection with the natural world. He refers to a bee sipping nectar, a very common and in fact pleasurable thing for a bee yet it is vastly turning into poison.

Sometimes there are no warning signs. It is precisely the fact that joy will come to an end that makes the experience of joy such a ravishing one; the fact that beauty dies makes the experience of beauty sharper and more thrilling. However, there are many contrasts as beauty is represented but also taken away by melancholic imagery. Like a weeping cloud is a very significant simile as nature is represented negatively although it is a common action, rain. However, weeping represents the idea of sadness and grief. Rain is not generally a negative aspect of nature. The contrast to the weeping cloud is made when this rain is able to foster the droop-headed flowers showing melancholy is also nourishing like the rain which revives the drooping flowers. Here Keats has built up an extended metaphor. The rain is very significant as it also hides the green hill showing melancholy to cover up natures finer aspects. The colour imagery of green suggests fertility, beauty and aliveness; this is the contrast of joy and melancholy. Rain and sadness are able to hide natures beauties. This contrast is almost made in April shroud which has oxymoronic ideas as April is the month of natures renewal, a pleasant setting and shroud is a cloth used for death. This portrays the idea of the mutability of life. Sadness needs to be accepted in order to enjoy lifes pleasures. Nature is a source of melancholy and like some aspects of nature, such as rainbows and waves, melancholy is not always long lasting. It is meant to be temporary, as life has many emotions through the human world as well as the natural world. Ode on Melancholy Essay Example Ode on Melancholy Paper The differences highlighted between Ode to a nightingale and To Autumn is, their way of accepting is based on different concepts. To Autumn does so in a positive way whilst Ode to a Nightingale does not. To Autumn can be related to Ode on Melancholy; their ideas on life are similar. Ode on Melancholys theme is based on the idea that melancholy cannot be felt without feeling joy. Keats presents this through the view of Joy being unable to feel melancholy, save him whose strenuous tongue / Can burst Joys grape against his palate fine. The grape metaphorically presents the feeling of happiness and that it needs to burst and be fully tasted in order for melancholy to be completely felt or understood. To Autumn is similar in the sense that Keats understands that life and death come with each other, you cannot experience spring without experiencing the robin red breast in winter. To Autumn also makes the distinction between life and death and how they cannot be without each other when he says full-grown lamb. Lamb presents new birth and the idea of a full life ahead, whereas full-grown presents old and near death.

Both Ode on Melancholy and To Autumn express the inability to have something without the other. There is however a distinct difference in the language used in both poems. Ode on Melancholy is very negative and filled with negative images whilst To Autumn is more positively generated and filled with positive descriptions. Throughout Ode on Melancholy Keats uses negative emotions, images and ideas. Such as Sorrows mysteries and drown. Sorrow presents depression, sadness and grief which promote a negative impression to the reader. Also the use of sibilance in Sorrows mysteries, also contributes to the negative feel as it creates an eerie and sinister atmosphere. Drown is particularly violent image of death creating fears and worry. This aura is created throughout the poem, other words such as weeping, droop-headed flowers and rich anger are also used. Weeping again creates sadness and a feeling of distress. Droop-headed flowers takes the negative imagery to a natural level droop-headed is the stance of a dead flower through which Keats is using death images on nature, whilst also creating an idea of the flower drooping its head in sadness. To Autumn on the other hand is filled with positive imagery and ideas such as, fruitfullness and ripeness. This gives the idea of fertility and birth, which are considered beautiful images as it is the impression of new life and the start of living. Again Keats continues this positivism through the poem, through words such as sound asleep, patient look and drowsed, these also creates positive images. Being sound asleep creates connotations of being relaxed and in a place of calm and serenity. Patient look creates the same type of aura, that life is calm and simple; full of neither patience not worry nor distress. It is clear that Ode on Melancholy is very negative and To Autumn is particularly positive in its presentation what also makes them similar is that Keats has created an image and run it through the entire poem without change but a continuous feel of the same emotion be it negative or positive. The way in which To Autumn stands out from the other odes is its outlook on life and death, and its ability to fully accept both from the offset. The other odes however have a begrudging ability to accept anything. To autumn is the only of the poems which does not have ten lines in its stanzas, it is as if the eleventh line is that extra bit of understanding and positivism, the extra space to be able to accept death. To Autumn is a far more inspirational and beautifully positive poem creating a placid, relaxed and loving view whilst the others tend to make us, the reader, feel down and miserable as they have a much more pessimistic view on life.

ACT Homeschool Code for Registration

ACT Homeschool Code for Registration SAT / ACT Prep Online Guides and Tips If you've registered for the ACT, you may have noticed that you'll need to enter a school code. But what code do you put if you're homeschooled? How can you make sure your scores get to you? We answer your questions in this guide! What Is the ACT Homeschool Code? The universal ACTHomeschool Code is 969-999.This code is applicable anywhere in the USA, and it's what you'll use when asked to provide a school code. When you use this ACT homeschool code, itmeans that your score results will be sent directly to your home. You will have already provided your address in a different part of the registration process, and ACT will use that information to know where to send your scores. Why Does the ACT Ask for School Codes? There are two reasons why students are asked to provide a school code when they register for the ACT. The first is so their school can see how well they and other students are doing on standardized tests. The second reason is that ACT uses this information itself to collect data on how well different groups of students do on the exam.This can include comparing scores of students within one local area, comparing scores of students in different states, and comparing scores of students in public schools vs home schools.Homeschooled students, on average, score higher on the SAT and theACTthan their public school counterparts. When Should You Use Your Local High School's Code? If you want to, you can use the local high school's code instead of a homeschool code,as long as you have permission from the high school. This could be a good option if you plan on attending the high school later on and want them to already have your ACT scores, or if you need to provide them your ACT scores to participate in their extracurriculars. Conversely, this could mean less privacy for you, since the high school officials would then be able to view your ACT scores. If that bothers you, then it might be better to use the ACT homeschooler's code and send your scores directly to your residence.

Psychological and spiritual conquest Essay Example | Topics and Well Written Essays - 250 words

Psychological and spiritual conquest - Essay Example The Confession Manuals depict lust as the most prevalent sin, above drunkenness, lying, murder or stealing and did not value the Indians’ norms that governed the transition into adulthood. This portrays the missionaries as a group of self-righteous people who are out to satisfy their own lust, despite accusing the Indians of lust. They are missionaries who are expected to be well conversant with the 10 commandments, but are only focused on the sixth one. It does not help that they even raped virgin Indian women. On the Indians’ part, they may have punished both men and women equally for sexual transgressions, but they also had their unconventional norms that allowed them to dissolve marriages or change partners for reasons that seemed purely for adventure. In conclusion, the reading brings forth both the missionaries and Indians as having unconventional norms, albeit the fact that the norms have guided their lives before encountering each other. The different values come out distinctly as inappropriate for the modern

Criminal law Essay Example | Topics and Well Written Essays - 500 words

Criminal law - Essay Example Moreover, there are instances where the concept of crime within a particular country changes as society adapts to the tides of time. What used to be a crime yesterday is now legal today. A classic example for the changing concept of crime over a period of time is the case of defamation which had been decriminalized through the amendment to the Coroners and Justice Act in 2009 (OSCE). UK lawmakers have decided to relax the definition of crime insofar as defamation is concerned to make more room for the right to freedom of speech. This will remain true until the parliament decides to make further changes to the law on defamation. On the matter of relativity of crime in different jurisdictions, a good example would be possession of cannabis. There is no common consensus among the governments of the world as to the dangers and benefits of the plant and its derivatives. The countries that see more benefits have already legalized it, under certain conditions, while those who insist that ca nnabis does more harm than good continue to make its possession and use as a crime punishable with penalties ranging from light to life imprisonment and even death penalty. In the UK, possession and use of cannabis in any form is a crime but in Peru, it is perfectly legal.

The Branches of Government - Research Paper Example This is inclusive of the president who also cannot function as they please. Other parties in the government also have the right to impose the vote of no confidence on the president. Due to the tendency of many governments to usurp power, analysts argue that if left to run governments, a lot of leaders would end up running countries as private businesses. However, Campbell indicates that in the US the case is totally different (2). The constitutional makers of US divided the government into sections that would specialize in formulating laws, another section that would implement the laws formulated whilst the last the section would see administration of justice in the country. The Congress was mandated to be the law makers in the government whilst the president through the backup from the departments and agencies in the executive arm of the government to put in force the laws put in place. In line to this proposition, it is justified to argue that the president heads the non elected members of the government. It is also vital to note the establishment of the Supreme Court by the judicial authorities (Campbell, 111). This clearly aided in the checking the systems put in place in the government. The states and the citizens also have their administration authorities through the state governmental units present in all states. This is referred to as the governmental units that are legally authorized to operate within their jurisdiction. Of essence, the Executive that comprises of the president, vice president and cabinet members plays the role of ensuring that the daily operations of the country function effectively, such collection of duties, representation of the country in international forums, and safeguarding the country’s security amongst others (Campbell, 25). The Legislature, which comprises of the congress make up laws, and ensures

Perception Of Interpersonal Relationships English Language Essay

Perception Of Interpersonal Relationships English Language Essay Learning the perception of Interpersonal Relationships the past few weeks have been a very rewarding experience for me. I have always enjoyed talking to people, listening to people, and just being around people, but I never really knew just how important communication was and being able to do it effectively. Ive learned many things in this course, but my focus for this paper is going to be interpersonal relationships. What are interpersonal relationships? Interpersonal Relationships are very important when dealing with any kind of friendship. It is interaction with another person, usually in an informal setting, and is one of the best ways to develop and retain an association. In order to do this, you must have the ability to understand and get along with others. This is known as emotional intelligence: being self-aware, managing emotions, encouraging yourself, recognize emotions in others, and managing associations. Self-awareness is having the capability to get a little distance from the emotion so that you will be able to look at it without being overwhelmed or react too promptly. Managing your emotions is expressing them in an approach that is suitable to the situation. Motivating yourself is setting a goal and disciplines yourself to do what you have to do in order to reach that goal. Recognizing emotions in others is having Empathy, which you are capable of recognizing and sharing someone el ses feelings, and its essential to human associations. In order to handle relationships, you must be capable of organizing others, and negotiating solutions when there are problems to be solved, and generally bond with others emotionally. You must also have a sense of balance and be capable of recognizing your own needs and know how to execute them. There is importance of emotional intelligence to strategic flexibility. You must have strong self-concept, which is the way you think about and rate yourself. The way you perceive people and the planet around you, and how fine you comprehend and cope with others have nonstop influence on your self-concept. Perception, emotional intelligence, and self-concept have a nonstop manner on strategic flexibility because they can either improve or weaken your capability to expect, evaluate, estimate, choose, and relate your skills and behaviors. The healthier your perceptive skills, the more probable your emotional intelligence is high and your self-concept is encouraging. While becoming familiarized to using strategic flexibility framework, you build up self-control through self-discipline. Listening to others becomes easier when you are secure in yourself. Your perceptions are more precise, your interpretation of nonverbal behavior of others and attempts to actually comprehend improves. There is a larger chance that you will be capable of managing relationships more productively. Managing relationships is not an easy job. It is a learned behavior, and by having emotional intelligence can help you launch and prolong enduring, significant relationships. Physical attraction is paying attention to somebody for the reason of the way they look. The attraction can also be sexual. It can be a reason for wanting to get to know someone, but is not usually the foundation for a durable relationship. Perceived gain is when we are mesmerized by someone because we assume we have something to achieve from them. We typically inquire about others in our same category, but for a moment we try to intermingle in with a higher category because we assume the awards will be of greater value. Similarities are when we are mesmerized by someone because we share our attitudes and beliefs or seem knowledgeable about topics that are of concern and importance to ourselves. Our beliefs are convictions; our attitudes are the felt beliefs that preside over how we conduct ourselves. Compatibility is having related attitudes and personality, and enjoying the same activities. Differences are when people have very different beliefs. This is usually very unlikely that a well-built and enduring relationship will be produced. But it is possible for people with different personality characteristics to be mesmerized by each other. Proximity is the close contact that occurs when people share an experience with each other such as work, play, or school. Another type of attraction is cyber attraction, which is when we depend on cues such as verbal communication, mode, time, tempo of text, and utilization of punctuation and emoticons. This gives us the chance of interacting with others exclusive of the influence of physical attractiveness stereotype and the less significant number of cues has larger importance. A motive for interpersonal communication varies from person to person for the reason that each person has their own personalities and moods. When we take on a lot of interpersonal communication for pleasure, it is because it is fun. Affection is very important to happiness, whether it is articulated verbally or nonverbally. It is a heart-to-heart emotion. Inclusion is your association with others and is the most powerful human need. Belonging is everyones sense of well-being. Escape is used when we try to avoid doing something that we need to do. The newest form of escape is by computer. Chat rooms, e-mail, and surfing the net are ways of escaping without actually going anywhere. Relaxation is done to relax and unwind after dealing with the various activities of the day. Control is when you are capable of making choices. When it comes to health, it has been researched and shown that people with strong social ties live longer than those that isolate themselves. People whom are lonely are encouraged to join local clubs or organizations because of health-protective things. Cyber motivation is usually an amplified motivation because engaging in CMC is pleasurable and stimulating. It also has the capability of boosting self-esteem, and you are able to self-disclose with little risk of losing face. Relationships are governed by roles that the participants look forward to each other to play. They are for a time firmly clear; and at other times the participants have the flexibility to identify them. The foundations for conversations are usually started with small talk. This allows a person to continue contact without making deep commitments. Some tips for the foundation of conversations are as follows: introduce yourself in a way that allows the person the opportunity to respond to you; give him/her a way to remember your name; and personalize your greeting. Bids and the bidding process is what hold relationships together. Bids are questions, gestures, looks, touches, or a distinct look so as to say I would like to feel attached to you. Responses to a bid can either be a positive or a negative answer to the call for emotional connection. Owned messages are acknowledgements of subjectively with the use of first person singular terms (I, me, my, mine). Self-disclosure is when a person tells another person something that they wouldnt typically make known to just anyone. Social penetration is the development of escalating both disclosure and intimacy in a relationship. It is the majority of the most extensively studied process in relational development. The process of self-disclosure is divided into four sections, know as the Johari Window. The first section is the open pane, which includes information about yourself that you are willing to communicate with others, and you are unable to hide. The second section is the blind pane, which is kind of an accidental disclosure area. These are things that you dont know about yourself, but others know about you. The third section is the hidden pane, which is self-knowledge that is hidden from others. These are things you know about yourself that you dont want disclosed to others. The last section is the unknown pane, which is a nondisclosure area without any possibility of being disclosed because it is not known by you or by others. Self-disclosure is most rewarding when it leads to greater intimacy. Intimate relationships allow us to really be who we are and share who we are with another person. It should only occur in relationships that are of most importance to us. The essential elements of good relationships are: vocal skills, arousing self-expression, chatty focus, nonverbal examination, chatty support, concern and enjoyment, dedication, and adjustment. Vocal skills are having the ability to carry ongoing conversations, or dialogues with your partner about the relationship itself. Emotional Expressiveness is your ability to bid and respond to bids based on the way your brain process feelings, the way your emotions were maintained in your home, and your emotional communication skills. Conversational Focus is what you and another person agree to talk about. Nonverbal Analysis is your capability to interpret amid the lines and explore nonverbal cues of another person. Conversational Encouragement is vocalizations that reveal to someone that you are listening and interested, and prompts them to go on with talking and intricate their own ideas. Care and appreciation is a way of consistently using ways to communicate with a person whether you want a relationship with that person or whether you want to avoid that person. It is used mainly to foster a relationship. Commitment is the strong need by both parties for the relationship to go on and an eagerness by both parties to take accountability for the problems that come about in the relationship. Adaptation is the time and effort devoted to sustaining, heartening, and cultivation relationships, even the deep-rooted ones, and must be spent in both introspection and communication. It is important for you to speak, listen, agree, stay on track, and hold your relationship in an affectionate view. Another way of forming interpersonal relationships is by the internet. You can benefit from internet communiquà © because it promote vigorous contact and relations, offers stronger support systems for interpersonal relationships, allows people to be integrated into society and removes some barriers, reduces the cost of communicating with geographically distant acquaintances and strangers, increase social contacts beyond family and close friends, offers opportunities for communicating on an global altitude, and loosen the communal limitations that have traditionally protected morality and manners. Internet addiction can also be a problem. But it still affirms, reinforces, and assists in maintaining successful interpersonal associations. These are all the tools that aide in holding a relationship together. If you are not capable of adapting and adjusting your skills and behaviors, these tools are ineffective. So, it is very important to learn and develop strong communication skills so that you can be more effective in your interpersonal relationships. Communicating Effectively, Eight Edition by Saundra Hybels and Richard L. Weaver II.

Essay --

Colour vision refers to the ability of an organism to distinguish between stimuli based on the wavelengths of light they emit, reflect or transmit. We live in a world filled with colours which we use as an advantage on a day-to-day basis; to signify danger, make things stand out and to help us categorise the world around us. However, 1 in 12 males and 1 in 200 females (approximately 4.5% of the population) suffer from some sort of colour vision deficiency or blindness (Colour Blind Awareness, 2014). It is therefore of interest to investigate what is different about the visual system in this minority and why the occurs. This essay will investigate this by considering what ‘colours’ actually are in terms of wavelengths of light, investigating the differences of what we perceive to be a ‘coloured’ world based on the different visual systems of non-human animals. Finally it will look at what makes the system of colour blind humans different, questioning whether we can really consider them colour blind at all. The basis of our vision is a direct cause of photons (light) entering our eyes from the environment around us. We examine these photons in one of two ways; either the intensity of the light (number of photons) or by examining the wave energy. This wave energy is what enables colour vision, and refers to our eyes ability to detect slight changes across the electromagnetic system of light. As a whole this consists of a variety of parts; cosmic rays, gamma rays, x-rays, ultra-violet light, visible/white light, infrared, microwaves and radio waves. Our human eyes are only sensitive to the visible white-light which ranges from approximately 400 to 700 nanometres (nm) across the electromagnetic system. Newton is heavily credited towa... ...t differences in colour therefore relies on the sensitivity of different types of cone cell within our retina. This is what enables us to see the full spectrum of visible light from blues into the deep reds. It is evident from studies with dogs, birds, snakes and other animals that having a different number of cones, or having these cones sensitive to different wavelengths causes a completely different perspective of our colour world. As a result Dichromatic or Monochromatic humans who are missing a certain type of cone(s), or even trichromatic humans with a cone sensitive to an anomalous wavelength can be labelled as colour blind. Whilst these ‘colour blind’ individuals are usually still able to detect differences in colour across the visible spectrum of light they ultimately see the colour world in an abnormal way to an individual with a normal visual system.

According to Arlov Grammatically

Many instructors urge their students not to start their sentences with the word â€Å"but†, or any other coordination conjunction for that matter. This can be disheartening for students because we commonly speak with our sentences beginning with a conjunction. However, writing is not like speaking. There are two schools of thought on beginning a sentence with the word, â€Å"but†. According to Arlov, â€Å"Grammatically, it is correct to start a sentence with but or any other FANBOYS conjunction.However, your instructors may discourage the practice for two good reasons† (343). She goes on to list the reasons. One good reason not to begin a sentence with the word but is because it is informal and casual. Academic writing is not usually casual or informal, and using â€Å"but† at the beginning of a sentence may make a more formal paper appear less than well thought out.While it is OK for some sorts of writing such as narrative or dialog, a professional paper is seldom written with coordination conjunctions at the beginning of sentences. Also, using words like â€Å"but† is addictive! It is easy to use and overuse. Arlov advises using conjunctions to begin sentences sparingly so as not to make it a hard habit to break. The other side of the issue says using but is just like using any other word to begin a sentence, and therefore, there is nothing wrong with it.

The Process For Firing a Government Employee

The Process For Firing a Government Employee The federal government’s disciplinary personnel process have become so cumbersome that only about 4,000 employees a year 0.2 % of the total workforce of 2.1 million are fired, according to the Government Accountability Office (GAO). In 2013, the federal agencies dismissed around 3,500 employees for performance or a combination of performance and conduct. In its report to the Senate Homeland Security Committee, the GAO stated, â€Å"The time and resource commitment needed to remove a poor performing permanent employee can be substantial.† In fact, found the GAO, firing a federal employee often takes from six months to over a year. â€Å"According to selected experts and GAO’s literature review, concerns over internal support, lack of performance management training, and legal issues can also reduce a supervisor’s willingness to address poor performance,† wrote the GAO. Remember, it actually took an act of Congress to give the Secretary of the Department of Veterans Affairs the power to outright fire senior VA executives who failed to meet performance standards. As the GAO noted, the in 2014 annual survey of all federal employees, only 28% said the agencies they worked for had any formal procedure for dealing with chronically poorly performing workers. The Probationary Period Problem After being hired, most federal employees serve a one-year probationary period, during which the lack the same rights to appeal disciplinary actions – like firing – as employees who have completed probation. It is during that probationary period, advised the GAO when the agencies should try their hardest to identify and carve out the â€Å"bad word† employees before they gain the full right to appeal. According to the GAO, about 70% of the 3,489 federal employees fired in 2013 were fired during their probationary period. While the exact number is not known, some employees facing disciplinary actions during their probationary period choose to resign rather than have a firing on their record, noted the GAO. However, reported the GAO, work unit managers â€Å"often do not use this time to make performance-related decisions about an employee’s performance because they may not know that the probationary period is ending or they have not had time to observe performance in all critical areas.† As a result, many new employees fly â€Å"under the radar† during their probationary periods. ‘Unacceptable,’ Says Senator The GAO was asked to investigate the government firing process by Sen. Ron Johnson (R-Wisconsin), chairman of the Senate Homeland Security and Governmental Affairs Committee. In a statement on the report, Sen. Johnson found it â€Å"unacceptable that some agencies let the first year slip by without conducting performance reviews, never aware that the probationary period had expired. The probationary period is one of the best tools the federal government has to weed out poor-performing employees. Agencies must do more to evaluate the employee during that time period and decide whether she or he can do the job.† Among other corrective actions, the GAO recommended the Office of Personnel Management (OPM) the government’s HR department extend the mandatory probationary period beyond 1-year and include at least one full employee evaluation cycle. However, the OPM said extending the probationary period would probably require, you guessed it, â€Å"legislative action† on the part of Congress.

Interference, Diffraction the Principle of Superposition

Interference, Diffraction the Principle of Superposition Interference takes place when waves interact with each other, while diffraction takes place when a wave passes through an aperture. These interactions are governed by the principle of superposition. Interference, diffraction, and the principle of superposition are important concepts for understanding several applications of waves. Interference the Principle of Superposition When two waves interact, the principle of superposition says that the resulting wave function is the sum of the two individual wave functions. This phenomenon is generally described as interference. Consider a case where water is dripping into a tub of water. If theres a single drop hitting the water, it will create a circular wave of ripples across the water. If, however, you were to begin dripping water at another point, it would also begin making similar waves. At the points where those waves overlap, the resulting wave would be the sum of the two earlier waves. This holds only for situations where the wave function is linear, that is where it depends on x and t only to the first power. Some situations, such as nonlinear elastic behavior that doesnt obey Hookes Law, would not fit this situation, because it has a nonlinear wave equation. But for almost all waves that are dealt with in physics, this situation holds true. It might be obvious, but its probably good to also be clear on this principle involves waves of similar type. Obviously, waves of water will not interfere with electromagnetic waves. Even among similar types of waves, the effect is generally confined to waves of virtually (or exactly) the same wavelength. Most experiments in involving interference assure that the waves are identical in these respects. Constructive Destructive Interference The picture to the right shows two waves and, beneath them, how those two waves are combined to show interference. When the crests overlap, the superposition wave reaches a maximum height. This height is the sum of their amplitudes (or twice their amplitude, in the case where the initial waves have equal amplitude). The same happens when the troughs overlap, creating a resultant trough that is the sum of the negative amplitudes. This sort of interference is called constructive interference because it increases the overall amplitude. Another non-animated example can be seen by clicking on the picture and advancing to the second image. Alternately, when the crest of a wave overlaps with the trough of another wave, the waves cancel each other out to some degree. If the waves are symmetrical (i.e. the same wave function, but shifted by a phase or half-wavelength), they will cancel each other completely. This sort of interference is called destructive interference and can be viewed in the graphic to the right or by clicking on that image and advancing to another representation. In the earlier case of ripples in a tub of water, you would, therefore, see some points where the interference waves are larger than each of the individual waves, and some points where the waves cancel each other out. Diffraction A special case of interference is known as diffraction and takes place when a wave strikes the barrier of an aperture or edge. At the edge of the obstacle, a wave is cut off, and it creates interference effects with the remaining portion of the wavefronts. Since nearly all optical phenomena involve light passing through an aperture of some kind - be it an eye, a sensor, a telescope, or whatever - diffraction is taking place in almost all of them, although in most cases the effect is negligible. Diffraction typically creates a fuzzy edge, although in some cases (such as Youngs double-slit experiment, described below) diffraction can cause phenomena of interest in their own right. Consequences Applications Interference is an intriguing concept and has some consequences that are worth note, specifically in the area of light where such interference is relatively easy to observe. In Thomas Youngs double-slit experiment, for example, the interference patterns resulting from diffraction of the light wave make it so that you can shine a uniform light and break it into a series of light and dark bands just by sending it through two slits, which is certainly not what one would expect. Even more surprising is that performing this experiment with particles, such as electrons, results in similar wave-like properties. Any sort of wave exhibits this behavior, with the proper set-up. Perhaps the most fascinating application of interference is to create holograms. This is done by reflecting a coherent light source, such as a laser, off of an object onto a special film. The interference patterns created by the reflected light are what result in the holographic image, which can be viewed when it is again placed in the right sort of lighting.
