  • Shallow Water Waves Wind
    409 words
    Savage Seas The Wave Machine The wave machine is a simulator that will allow you to create an ocean wave and determine its height. Most ocean waves are formed when the wind blows across the water's surface. The wave height is determined by three factors: wind speed, fetch, and duration. Wind Speed In 1805, Sir Francis Beaufort, observing the effects of wind speed upon the sea, devised the Beaufort Wind Scale. Though wind speed is not the only factor in determining wave size, the Beaufort scale r...
  • Third Wave Feminists Need
    1,922 words
    Feminism was a very political movement during its first and second waves. The new Third Wave of feminism is quite different from the previous two. These three feminist writers all shed light on the views of modern feminists. Katie Roiphe has contributed to the New York Times Magazine and Playboy. She has also published two books, The Mourning After: Sex, Fear, and Feminism on Campus, and more recently, Last Night in Paradise: Sex and Morals at the Century's End. Roiphe's essay The Independent Wo...
  • Changing The Frequency Of The Wave
    668 words
    Physics Waves Lab SL Introduction: This lab will investigate the properties of mechanical waves such as a longitudinal wave, focusing on the question: Does a change in the frequency of a wave result in a significant and convincing change in the speed of the wave? Hypothesis: Changing the frequency of the wave will not result in a change in speed because the wavelength will change proportionally as in theory. Student Designed Investigation Procedure / Planning Procedure: 1. Three students would g...

  • Effect On Radio Wave Propagation
    2,604 words
    Propagation as defined by Webster Dictionary as "the phenomenon of radio frequency energy traveling through the earth's atmosphere, as well as through the empty space above the atmosphere". Once radio-frequency energy has been emitted from an antenna it will travel away from the antenna, where it is generated from, at the speed of light. Once it is sent the wave exists and propagates independently of the system that produces it. This means that changes, which occur at the transmitter (antenna), ...
  • Sound Waves With A Given Frequency
    504 words
    Resonance RESONANCE: ' The property whereby any vibratory system responds with maximum amplitude to an applied force having the a frequency equal to its own. ' In english, this means that any solid object that is struck with a sound wave of equal sound wave vibrations will amplitude the given tone. This would explain the reason why some singers are able to break wine glasses with their voice. The vibrations build up enough to shatter the glass. This is called RESONANCE. Resonance can be observed...
  • Air Column The Phase Of A Wave
    1,123 words
    INTERNATIONAL BACCALAUREATE SUBSIDIARY LEVEL WAVES SUMMARY 4.1 Travelling wave characteristics A medium is a material through which a wave passes. When a wave passes, each part of the medium moves away from its normal position and then returns. This is called an oscillation. Oscillations within the medium are slight movements either side of the normal position. The wave motion is the disturbance that passes through the medium. A wave pulse causes the medium to have one oscillation. A continuous ...
  • Perfect Wave
    963 words
    Surfing has been around for many years, in fact since 400 A. D and people are still going hard at it today and will for many more years to come. The very first surfers were the Island folk who would use the waves to get over the coral reefs and back to shore after their hard days of fishing. They found that this was the easiest and quickest way of transport over the reefs so they continued to do it for many years. As time went on the art of riding waves then developed into more of a 'leisure spo...
  • New And Old Waves Of Imperialism
    465 words
    Old and New Imperialism There were two different time periods where Imperialism occurred. The first wave of imperialism, called the "Old" Imperialism, lasted from around 1500-1800. The "New" Imperialism lasted from around 1870-1914. The three main differences that we will discuss today are the differences in economics, politics, and the motive behind all of this. The new and the old waves of imperialism were very much different through economics. The old economics was pretty much all about tradi...
  • Shallow Water Waves
    505 words
    The phenomenon we call a tsunami is a series of waves of extremely long wavelength and period generated in a body of water by an impulsive disturbance that displaces the water. Although tsunamis are often referred to as 'tidal waves' by English-speaking people, they are not caused by the tides and are unrelated to them. Tsunamis are primarily associated with earthquakes in oceanic and coastal regions. When an earthquake occurs, the energy travels outward in all directions from the source. This c...
  • Fourier Analysis
    631 words
    Fourier analysis of spatial and temporal visual stimuli has become common in the last 35 years. For many people interested in vision but not trained in mathematics this causes some confusion. The use of these Fourier methods does not mean that the visual system performs a Fourier analysis. At present it should be understood that this approach is a convenient way to analyze visual stimuli. Jean Baptiste Fourier, a mathematician, showed that any repetitive waveform can be broken down into a series...
  • Tsunamis And Tidal Waves
    465 words
    Tsunami A tsunami is a large water wave that is generated by seismic activity in or underlying layers known as faults. These enormous wave have historically affected many ways of life and still lie as a major factor for destruction in our coastal communities throughout the world. A tsunami is a wave chain or series of waves that is generated in a body of water by sea disturbance that vertically displaces the water. Earthquakes, landslides, volcanic activity and even cosmic materials can generate...
  • Differnece In Pressure Between The Sound Wave
    401 words
    In this chapter we studied sound waves. In this paper you will read about how the ear works, how acoustics work and how sound waves are used in real life in medicine and music. Some basic characteristics of sound waves. Sound waves are detectable to the human ear when the range is within 20 to 20,000 Hz. Sound waves are compressional waves also know as longitudinal waves. Sound waves require a medium to travel through. A medium is a substance or state of matter that the waves flow through. All s...
  • Vibrating Tines Of A Tuning Fork Sound
    1,363 words
    Sound is part of our everyday lives. Just like we have eyes for, we are given ears for hearing sound. We rarely take the time to think about the characteristics of sound and the ways that they are made. The basis for an understanding of sound and hearing is the physics of waves. Sound is a wave, which is created by vibrating objects and spread through a medium from one location to another. In this paper, we will look at the nature, properties and behaviors of sound waves. A wave can be described...
  • Distinctive Style For French New Wave Films
    1,559 words
    The French New Wave The French New Wave, also called La Nouvelle Vague in French, refers to the work of a group of French film-makers between the years 1958 and 1964. This core group of directors included Francois Truffaut, Jean-Luc Godard, Claude Chabrol, Jacques Rivette and Eric Rohmer. All of them had been film critics for the magazine Cahiers du Cinema. This group was very critical of the glitzy films made for the studios in France and Hollywood in the 1950's and 1960's; however, they admire...
  • Unhappy As The Wave
    720 words
    My Life With The Wave is about a man who takes home a wave from the ocean. I think his relationship with the wave can be compared to the relationship of a man and woman. At first he "meets" the wave in the ocean and as he is walking away he feels the other waves "staring" at him. This could be because he is taking the water away from where it should be, but the wave wanted to go like a woman who wants only what she wants and won't listen to anyone. When the man gets on the train he realizes he h...
  • Great White Wave
    857 words
    The Great Wave: Hokusai In the painter's eyes, he sees a motionless picture that will never continue on to become reality. Without the poem, the picture, an innocent bystander has no clue as to what is going to happen. This person is portraying what is inevitable of the three boats. The doomed fate is this great white wave is going to crush, beat and swallow these men in an instant. No time to react, no time to think, and no time to even say a prayer. The picture presents a multi faceted appeara...
  • Feminist Movement
    534 words
    "Would you describe yourself a feminist?" I was recently asked. Yes, was my knee-jerk reaction to the above question. I am a FEMINIST (in caps, no less.) I went to an all-women's college, I support reproductive rights and signed petitions to protect Roe vs. Wade as the decision approached its 30th anniversary, I believe that women deserve respect, that women's lives have value independent of men, that equal pay for equal work is a given. I've read Gloria Steinem, Aud re Lorde and Andrea Dworkin....
  • Use Tidal Energy
    1,060 words
    There are many natural renewable energy resources that we use in the world today such as wind, solar and tidal. These sources of energy are good because they are renewable, which means that they will never run out in our lifetime. So we can use them many times and they will always be there. This essay will be exploring one specific natural energy source, tidal energy. The topics being explored in this essay are how it is being practiced, where we can find this source being used in Canada / world...
  • Waves Break Closer To The Shore
    1,612 words
    The Erosion of Long Island's Barrier Beaches The barrier beaches, which line the south shore of Long Island are in a constant state of change due to factor's such as wind, tides and wave action. "The term ' barrier' identifies one that protects other features, such as lagoons, salt marshes, and bays from direct attack from the open ocean' (Leatherman 1). The pebbles and sand of which these beaches are made constantly lifted and deposited in other areas. Currents created by tides and waves carry ...
