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

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

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

of an electronic wave packet in the unifonn field in the interelectrode space of the vacuum photodetector is investigated. It is shown that the dimensions of such a packet must be of an order or more then one micron. It is shown that such localized charges can give rise to abrupt pulses of the current in the external circuit of the photodetector. The determination ofparameters of such packet by powerful laser pulse scattered with is discussed. The motion of one-electron wave packet in the nonuniform

Alpha waves are regular‚ have medium frequency‚ and occur while resting. Beta waves are irregular‚ have a low amplitude‚ and occur while attentive. In stage one of the sleep cycle‚ we experience Theta waves‚ which have similar frequencies and regularity to Alpha waves. Stage two also involves Theta waves‚ but may also have short bursts of Alpha and Beta waves called sleep spindles‚ or Delta waves called k complexes. These are the two shallowest sleep

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

sound waves Sound is a series of compression waves that moves through air or other materials. These sound waves are created by the vibration of an object‚ like a radio loudspeaker. The waves are detected when they cause a detector to vibrate. Your eardrum vibrates from sound waves to allow you to sense them. Sound has the standard characteristics of any waveform. Sound is a waveform that travels through matter. Although it is commonly in air‚ sound will rapidly travel
