# WAVES AND ELECTRICAL ENERGY

###### PLAY
wave
a disturbance that transfers energy from place to place
energy
the ability to do work
frequency
the number of waves that pass a certain point in a given amount of time; measured in Hertz (Hz) - 1 Hz is one wave per second
wavelength
the distance between two corresponding parts of a wave (such as the distance from crest to crest or trough to trough)
amplitude
the maximum distance that the particles of the medium carrying the wave move away from their rest positions. The greater the amplitude, the greater the energy in a wave.
wave speed
how far the wave travels in a given length of time
mechanical wave
waves that require a medium to travel through
medium
the material that a wave travels through (air, water, etc)
transverse wave
a wave that moves the medium at right angles to the direction in which the wave is traveling
crest
the highest part of a transverse wave
trough
the lowest part of a transverse wave
longitudinal wave
a wave that moves the medium parallel to the direction in which the wave is traveling
compression
the part of a longitudinal wave where the medium is pushed together
rarefaction
the part of a longitudinal wave where the medium is spread apart
