Physics of Water Waves :: Lab Report

All waves possess the properties of reflection, refraction, diffraction and interference. These phenomena's were observed with the use of a ripple tank. A ripple tank consists of a large rectangular tray with a transparent bottom. Water is placed in this tan to a depth of approximately one centimeter. A light source is then placed above the tray of water. When the water is disturbed it can be seen on a white surface positioned under the tray. The first phenomenon observed was reflection. It was found that water waves also follow the law of reflection. As straight waves strike a hard straight surface they are reflected at an angle equal to the angle of incidence. After reflection the wave has the same speed, frequency and wavelength as it did prior to the collision. This is similar to the reflection of circular waves off a straight barrier. The reflected waves are also circular, however they have a centre point that is position behind the barrier. This point is known as the "image" of the source. Reflection of a parabolic or concave barrier can be closely compared to that of light waves off a concave mirror. If the incident wave was straight, the reflected waves are curved, and they converge at a fixed focal point. After passing through the focus, the radius of the curves increase. The opposite is so when circular waves strike a concave barrier. The reflected waves are then straight. The next phenomenon observed was the refraction of water waves. The refraction was demonstrated in the ripple tank by dividing the tank into a deep and shallow region. This was achieved by placing a rectangular object into one end of the tank. When straight waves travel from a deep region of water into a shallow region, it is found that the speed of the waves is slower in the shallower region. Since the frequency of the wave stages the same, it is obvious that there must be a corresponding decrease in wavelength. If the waves pass from deep to shallow water at an angle other than

Modernism and Modernist Literature

Christina Ortega March 30, 2013 Modernism and Modernist Literature Modernism is the movement in visual arts, music, literature, and drama which rejected the old Victorian standards of how art should be made, consumed, and what it should mean. The concept was what is reality? It used art and literature to replicate reality, and traditions cultivated in Romanticism and Victorianism. It was against all traditions. The Modernist Period in English Literature occupied the years from shortly after the beginning of the twentieth century through roughly 1965.The period was marked by sudden and unexpected breaks with traditional ways of viewing and interacting with the world. Experimentation and individualism became virtues, where in the past they were often completely discouraged. In the world of art, generally speaking, Modernism was the beginning of the distinction between â€Å"high† art and â€Å"low† art. Still, the most effective poets and novelists did manage to make deep statements that were absorbed by the whole of society and not just the writer’s inner circles.In Modernist literature, it was the poets who took fullest advantage of the new spirit of the times, and stretched the possibilities of their craft to lengths not previously imagined. In general, there was a disregard for most of the literary making of the last century. The following are characteristics of Modernism: †¢ Marked by a strong and intended break with tradition. This break includes a strong reaction against established religious, political, and social views. †¢ Belief that the world is created in the act of perceiving it; that is, the world is what we say it is. There is no such thing as absolute truth. All things are relative. †¢ No connection with history or institutions. Their experience is that of alienation, loss, and despair. †¢ Life is unordered. †¢ Concerned with the sub-conscious. Ambrose Bierce, turn of the century California's one of th e most notorious writers. Ambrose was known as Bitter Bierce and his motto was â€Å"Nothing Matters†. Although; Bierce's devastating short stories about the War Between the States–most particularly â€Å"An Occurrence at Owl Creek Bridge†.The first page and a half during which the condemned, Peyton Farquhar, is yet unnamed offers a clear description of a military hanging: how it is done, who stands where and who gives the orders, how gentlemen are not excused from the noose. Farquhar, after his escape, his senses supernaturally alert, notices something that would have been commented upon in the camps of the Civil War: the gray eyes of a sharpshooter. He remembers that he'd heard all of the most famous sharp-shooters have gray eyes.Then it turns out to be a mere dream of thought for Peyton. It was a sudden flash of what he would have wanted to happen. With the end of this story resulting in him seeing his wife at one last glance before the reality of his death. This story was written is a way that I the reader hadn’t quite was able to even distinguish that it was merely a dream of thought till the sudden death. The story was very vivid in detail and descriptive. Portrayed a sense of reality giving aspects of what could have happened.Gave me the reader a moment of shock when figuring out it wasn’t real and he had actually been executed. In conclusion the entire story was a great example of a modernist story. Gave me a great example of how he wrote a short store making me determine the true reality of it. This modernist literature definitely made a social statement. Made you realize how we as people do this all the time. I’ve been in many situations where I can imagine another outcome yet, reality strikes and I realize its happening. Works Cited 1.Lewis, Pericles. The Cambridge Introduction to Modernism.

Professional and Managerial Ethics Caselet Essay

Limaha Inc. is a world-renowned toilet manufacturer founded in 1967. Limaha led the innovation of advanced bathroom utilities and mainly caters to First Class airports and 5-star hotels. The recent Asian economy boom has led to increased demands of Limaha toilet bowls for the business expansion of their loyal clients. In response, the company has decided call for this unprecedented increase in production that must be met as soon as possible.Jenny Panaguiton, the purchasing manager of Limaha’s main office, was tasked to choose a supplier of premium porcelain to be used in the production of their patented No Pressure toilet bowls. This production will include a big production contract with a new posh hotel in the country’s capital whose construction is about to end with the installation of their bathroom fixtures. After careful analysis from 20 suppliers by the purchasing department, Jenny was presented and left to decide between two suppliers: O Mang China and Teddy B. Solutions. O Mang China offered superior porcelain at a high price. This price along with other costs necessary to deliver the porcelain to the production plants was estimated to exceed the company’s budget. Although Limaha can choose to go ahead and allocate more capital for this transaction, it could result to lower company profits if the previously agreed sales price of No Pressure toilet bowls is not increased. If Limaha decides to charge a higher price on their new product, there is a high possibility that the hotel client would back out from the contract and change to another toilet manufacturer for confirmed business ventures next year. Teddy B. Solutions, on the other hand, offered a lower price for the porcelain materials which is well within the company’s budget. Christopher Barrido, the company’s Vice President for Production even greatly encouraged Jenny on choosing Teddy B, as the really low price of the porcelain would bring significant favorable variances in their division’s costs. Not only would their division have a pretty image in front of the Board, there would even be a possible salary increase. He even promised Jenny of a bright future in the company if she makes the right decision. Jenny, however, doubts their VP’s motives, as Christopher would not normally recommend any supplier and would just leave the Purchasing Department on their decisions. She thinks Christopher’s actions have something to do with the generous gifts Christopher has been receiving recently from his long-time friend and classmate, Teddy B. Teddy B’s proposal is highly attractive when just considering the company’s profits. However, the production team who reviewed the samples from Teddy B showed results that were a far cry from O Mang’s porcelain. Materials from Teddy B produced inferior quality toilet bowls. The production team voiced out their concerns through Pie Bread, the production manager. Pie greatly discouraged the use of Teddy B materials to Christopher Barrido, arguing that the use of such materials would greatly affect their quality, and the name of Limaha Inc. could be tarnished through this. They were also very concerned that the hotel might withdraw previous arrangements with Limaha because of the fact that these inferior toilet bowls were simply not appropriate for the posh hotel. Christopher just won’t have any of Pie’s arguments. He argued that the employees under her department were only exaggerating about the quality of the samples. Teddy B has long been in the business of supplying porcelain, so he argued that the problem is not on the materials, but on the workers handling the production who are not being efficient enough to produce at the expected quality. Pie and Christopher’s debate had been long, and word travelled that Pie was even threatened of demotion if results with the Teddy B samples still would not improve. Needless to say, people from production are now pointing daggers to the purchasing department, as their decisions could cause them their jobs. And so Jenny tried to negotiate the price offer of O Mang China and asked for any other possible alternatives their company could have. Its owner, Osmong, however presented her a very outrageous offer. Osmong is her former lover from a very bad and traumatic relationship.  Osmong, feeling bitter, is still deeply in love with Jenny even after she broke up with him six months ago for a number of undisclosed reasons. Since the breakup, Jenny has vowed to never reconcile with this man again. In a desperate attempt to get Jenny back, Osmong offered to significantly reduce their price to go lower than that of Teddy B, if and only if, she agrees to go back together with him again. This new price would mean that there would be no need for a price increase on the No Pressure toilet bowl, and they could even attract more potential long-term customers because of their high-quality products at a really low price.  To add to the list of her worries, Jenny received a note to come to a private meeting in a nearby cafà © with Bea Wing, Limaha’s Internal Auditor. The meeting had been really stressful, as the topic was Teddy B’s alleged recent romantic interest with Jenny. Teddy has been sending Jenny many gifts and invitations to dinners since the start of the year, and they had gone to a few dates. Jenny, however, just treated their relationship as platonic, and concluded that nothing can come out of their business meetings. Bea however would not believe any of it. Bea had been married to Teddy B for three years. Sadly, a gap in their relationship has formed due to their busy schedules. She noticed her husband’s special attention to Jenny, and thought that a possible divorce could be coming to her soon if Jenny continues to â€Å"lead him on† with her business partnerships. Bea thinks that this new materials supplying contract could be the last straw. She later vowed, that if Jenny makes one wrong move on choosing her husband and destroy her marriage, she would definitely destroy her life. Jenny was visibly shaken, given that Bea really has the power to do so, with a few alterations on her department’s financial statement, and some words with Board of Directors regarding her process of choosing the material suppliers. Jenny really has a lot riding in this decision. The company profits, the production employees, her personal relationships, her co-workers, and her own job are at stake in this one important decision of choosing the supplier of porcelain for the No Pressure toilet bowl model. She could not afford to lose her job now, given that it is the only way for her to pay for the medical bills of her five dogs in the hospital. This one decision could make  or break her life. Even more so, she’s not even sure if it is right. What do you think would be the best action to take?
