Seismic waves‚ which are waves of energy that travel through the earth‚ and are a result of an earthquake‚ explosion‚ or a volcano that imparts low-frequency acoustic energy. There are two types of seismic waves‚ Body waves and surface waves. Body waves travel through the interior of the earth. Surface waves travel along the earth’s surface and through water. Seismic wave fields are measured by a seismograph‚ geophone‚ hydrophone or accelerometer. These are used to measure earthquakes. When

Kinematic Derivation of the Wave Equation http://prism.texarkanacollege.edu/physicsjournal/wave-e... KINEMATIC DERIVATION OF THE HARMONIC WAVE EQUATION AND RELATED TOPICS An extremely important type of wave in physics is the harmonic wave. This is a wave consisting of propagating simple harmonic oscillations or linear combinations thereof. Attach a weight to a spring and hang the spring so the weight is free to move. Then lift the weight straight up and release it; it will oscillate up and down

Seismic Waves What are seismic waves? Seismic waves are the waves of energy caused by breaking of rock within the earth or an explosion. These waves are the energy that travels through the earth and is recorded on seismographs. There are many different types of these waves‚ but the two main ones are the body waves that usually travel though in inner layer of the earth‚ and the surface waves that only move around the surface of the planet. Body waves travel through the inner layer of the earth

Journal Entry: Making Waves For this assignment you will need a rubber tube‚ a spring‚ or a rope. Tie one end to a fixed support and move it up and down to produce a wave. What type of wave are you producing? Describe it in terms of its motion relative to the direction of energy transport and in terms of whether it is electromagnetic or mechanical. Next‚ you will need a wide pan of water. Repeatedly dip your finger into the water to make a circular wave on the surface. What happens to the wavelength

Specific Heat of a Metal Post-Lab I. Purpose The purpose of this lab is to determine the specific heat of an unknown metal. II. Safety Wear goggles and lab apron at all times. Use caution when boiling water. Do not pick up hot beaker or hot metal with hands. Use tongs. III. Pre-Lab Questions 1. A 12.5 g metal is raised to 100C in boiling water. It is put into 82.8 g of water at 22.4C‚ and the water rises to 28.6C. Recalling that the specific heat of water is 4.18J/gC‚ use the equation above

7/16/12 Heat of Fusion Heat of Fusion for Ice Introduction: This lab report is a step by step process in calculating the heat of fusion for ice and to compare the differences between salt added to room temperature water and salt added to icy water. To calculate heat of fusion‚ one must understand heat of fusion. Heat of fusion is the amount of heat required to convert a mass of a solid at its melting point into a liquid without an increase in temperature. As difficult as this may sound‚

order to present their experiences of Korean Wave‚ this paper will be divided into four sections. The first section will describe demographic characteristics of the Korean Wave group in Asia. The second section is a literature review refering to the cultural background of Korean Wave including Korean pop music‚ drama‚ food and so forth. This is followed by an interview conducted with Helen and Hana giving information about their experiences of Korean Wave. The final section will state some steretyping

To demonstrate interference of light waves‚ Thomas Young allowed light from an illuminated single slit to fall on a pair of narrow closely-spaced slits. Explain: a. Why light from separate lamp bulbs can never produce an interference pattern? b. Why double slits used as above do give an interference pattern? How would the interference pattern differ
