• Electromagnetic Radiation Cycles Per Second
    794 words
    Electromagnetic radiation is defined as the emission and transmission of energy in the form of electromagnetic waves. An electromagnetic wave consists of two waves at perpendicular planes, on representing the electrical field while the other represents the magnetic field. This spectrum is split up into about 81 octaves, much like the octaves of sound, which scientists have categorized in order to depict the usefulness of the different properties. Theoretically, electromagnetic waves can be as lo...

    EARTHQUAKE REFERENCE FILES Earthquake, shaking of the earths surface caused by rapid movement of the earths rocky outer layer. Earthquakes occur when energy stored within the earth, usually in the form of strain in rocks, suddenly releases. This energy is transmitted to the surface of the earth by earthquake waves. The study of earthquakes and the waves they create is called seismology. Scientists who study earthquakes are called seismologists. (Websters p. 423) The destruction an earthquake ca...
  • Physics Lab Speed Of Sound In Air

    Compare and Contrast of The Metamorphosis by Franz Kafka and The Stranger by Albert Camus Existentialism is defined as a philosophical movement that human beings are completely free and responsible for their own actions. Existentialists will try not to cause waves and remain completely uninvolved with anyone because they do not want to hurt anybody. There is absolutely no such thing as an existentialist because he would have to be so uninvolved to the point where he would not be able to live at ...
  • Ultrasound Quick Project Sound Frequency Waves
    388 words
    Ultrasound - Quick Project Ultrasounds are sound waves with frequency beyond the human limits, therefore humans are unable to hear them. It even travels at exactly the same speed as sound in any medium. Humans can hear sound within the frequency range of about 20 to 20, 000 Hz, so any sound above 20 k Hz is ultrasound. Ultrasound or ultrasonography is a medical imaging technique that uses high frequency sound waves and their echoes. The technique is similar to the echolocation used by bats, whal...

    How Natural Processes Operate at Coastal Geographic Environment. Natural Processes are actions or events that have natural causes, which result in natural events. The three main coastal environment processes that operate at Muriwai are Coastal Erosion, Coastal Transportation and Coastal Deposition. The elements that interact to produce natural processes are wind, waves and tides. Each phenomenon at Muriwai's coastal geographic environment has been produced by interaction. Coastal Erosion is a p...
  • Waves Water Wave Tsunamis
    487 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...

By their united enthusiasm to find these 'sanctuaries'; people bring the cage of society with them. Very quickly it becomes necessary to erect bars to keep people out. William Tucker 'Is Nature Too Good For Us?' ; William Tucker's essay 'Is Nature Too Good For Us'; discusses the complications with the environmental movement to set aside pieces of land as wild...
  • Wind Chimes Rods Rod Waves

    Wind Chimes Wind chimes produce clear, pure tones when struck by a mallet or suspended clapper. A wind chime usually consists of a set of individual alloy rods, tuned by length to a series of intervals considered pleasant. These are suspended from a devised frame in such a way that a centrally suspended clapper can reach and impact all the rods. When the wind blows, the clapper is set in motion and randomly strikes one or more of the suspended rods -- causing the rod to vibrate and emit a tone. ...

    Gravity is really an unknown force. Wec an define it as a field of influence, and that it effects the entire existence of the universe. Some people think that gravity consists of particles called gravitons, which travel at the speed of light. The only thing we do know is how gravity operates in different parts of our universe. Without gravity, there would be no space and time. There is a legend that says that Galileo once dropped two objects off the Leaning Tower of Pisa to show that the heavie...
  • Earthquakes Focus Earth

    Earthquakes Earthquakes, one of the most destructive natural phenomena, consist of rapid vibrations of rock near the earth's surface. Because of their unpredictable occurrence and enormous capacity of destruction, they have brought fear to mankind since ancient times. A single shock usually lasts no more than a few seconds, but a series of smaller quakes may last for as long as five minutes. The quake felt on the surface is always the result, not the cause of some underground geologic process, a...

    Natures Undistinguished Elements On a typical fall day, Lake Michigan can speak a language of its own. The lake relates a story of flowing waves, bobbing boats, and soaring birds. As the white-crested, blue waves drift towards the foamy shores, they bring with them a long history. Many of these waves have traveled for miles to arrive here in Milwaukee, and as they reach the rocky shores, the long, rolling journey comes to an abrupt and ferocious end with waves crashing against the sides of jagge...
  • Tsunamis Tsunami Water Wave
    545 words
    A tsunami is a wave train, or series of waves, generated in a body of water. Earthquakes, landslides, volcanic eruptions, explosions, and even the impact of cosmic bodies, such as meteorites, can generate tsunamis. These waves can savagely attack coastlines, causing devastating property damage and loss of life. In English, the word tsunami means "harbor wave." Represented by two characters, the top character, "tsu," means harbor, while the bottom character, "nami," means "wave." In the past, tsu...
  • Sound Waves Wave Intensity Ear
    399 words
    Sound Waves Waves are disturbances that travel through a space while changing its matter. A sound wave is what allows us to hear sounds. It is created by vibrations, which are made by the movement of matter. Sound waves must travel through a solid, a liquid, or a gas. The more tight the particles, the faster the wave will travel. This would mean that a sound wave travels fastest through solids and slowest through gases. The speed that it travels through a liquid would come somewhere in between ...

    Earthquakes occur throughout the world but the vast majority of them develop along narrow belts. These belts are tens to thousands of kilometres long and mark the boundaries on the Earth's surface. The belts are considered very active geological wise. Earthquakes occur when rocks rupture under the pressure created by continues movement and collision of thin jigsaw-like tectonic plates found under the Earth's surface. Seismic waves (vibrations) are then created and proceed outwards in all direct...
