Introduction Mistakenly called "tidal wave" the word tsunami is a Japanese word meaning‚ "harbor wave". A tsunami is a series of traveling ocean waves of extremely long length generated by disturbances associated primarily with earthquakes occurring below or near the ocean floor. Tsunamis are primarily the result of a vertical displacement of water and rank high on the scale of natural disasters. Since 1850‚ tsunamis have been responsible for the loss of over 440‚000 lives and billions of dollars

to point through a medium is called a ___. a. period b. periodic wave c. wavelength d. pulse Answer: D A wave is a continuous and repeating disturbance of a medium and a pulse is a single disturbance. 2. If the particles of the medium are vibrating to and fro in the same direction of energy transport‚ then the wave is a ____ wave. a. longitudinal b. sound c. standing d. transverse Answer: A In longitudinal waves‚ particles of the medium vibrate to and from in a direction parallel

Electromagnetic waves in space See the book “Optics” by Hecht sections 3.2 and 3.3 Speed of light: EM waves travel in a vacuum with speed c = c = 299‚792‚458 ms-1 exactly They are transverse waves with (vector) E and B field orthogonal to each other‚ for this section bold indicates vector quanties. When far from the source (many wavelengths) the E and B fields are in phase The vector E x B points in the direction of motion Travelling waves can be written as E = E 0 ⋅ ei ( kx −ωt ) and B = B 0 ⋅ ei

research on radio waves‚ to us‚ radio waves were just waves going through the atmosphere‚ carrying sound from one place to another. Those were our ignorant days! We did not realize the complicated terms and theories involved. In the following report you will see how we advanced in our knowledge of radio waves‚ and we hope it will do the same for you. Radio waves are a combination of two kinds of electric vibrations. Audio frequency waves‚ which represent voice and other sounds and radio frequency

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

Radio Waves In the modern society‚ radio is the most widely used medium of broadcasting and electronic communication : it plays a major role in many areas such as public safety‚ industrial manufacturing‚ processing‚ agriculture‚ transportation‚ entertainment‚ national defense‚ space travel‚ overseas communication‚ news reporting and weather forecasting. In radio broadcasts‚ they use the radio waves which can be both microwaves and longer radio waves. These are transmitted in two ways: amplitude
