Waves work and power

Wave Waves are caused by vibrations of a Medium.
Medium The material (solid, liquid, gas) through which a wave can travel.
Transverse Wave Particles moving perpendicularly to the direction the wave travels.
Crest The point where the wave is at it's highest.
Trough The points where the wave is at it's lowest.
Longitudinal Wave Particles more back and forth in the same direction that the wave travels.
Compression When the waves are compacted together.
Rarefaction When the waves are spread apart.
Mechanical Wave Waves that require a medium.
Electromagnetic Wave Wave that can travel without a medium.
Amplitude A measure of how far particles in the medium move from their rest position.
Wavelength The distance from any point on a wave to the next identical point on the same wave.
Frequency The number of waves that pass a point in a given amount of time (usually one second).
Hertz(Hz) Frequency is measured in hertz and one hertz is equal to one wavelength per second.
Wave Speed The speed that the waves travel and that depends on the properties of the medium.
Force A push or pull exerted on an object in order to change the motion of an object measured in Newtons.
Work The use of force to move an object some distance measured in Joules.
Power The amount of worked used in a given amount of time measured in watts.
It took 500 newtons of force to push a car 4 meters. How much work was done? 2,000J (work=500N x 4M)
How much work is done using a 60 watt light bulb for 1 hour? 60J(work=60J x 1 hour/ Seconds)
