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

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

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

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

Characteristics and Nature of Waves In physics‚ a wave is a disturbance that travels through space and time‚ usually accompanied by the transfer of energy. Waves travel and the wave motion transfers energy from one point to another‚ often with no permanent displacement of the particles of the medium—that is‚ with little or no associated mass transport. They consist‚ instead‚ of oscillations or vibrations around almost fixed locations. For example‚ a cork on rippling water will bob up and down

Assignment 2- Plastic Pollution Case Analysis Plastic pollution is the pollution caused by the disposal and accumulation of plastic material into the environment. Plastic is now the most common material that is a basic essential in our everyday life. They are all around us in the form of plastic bags‚ containers‚ credit/ debit cards‚ stationary‚ electronic items and many more. Plastic is a material made up of organic synthetic or semi-synthetic degradable matter. This matter can be broken

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
