Physics Ch.25.1-11


Period = The time of a back-and-forth swing of the pendulum
crest = high point of a wave
troughs = the lowest point of a wave
amplitude = the distance from the midpoint to the crest or trough of the wave
wavelength = distance from the top of a crest to the top of the next one
frequency = the number of vibrations an object makes in a unit of time
hertz = the unit of frequency
transverse wave = right angles to the direction in which a wave travels.
longitudinal wave = when the particles are parallel to or along the direction of the wave, rather than a right angle.
