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. |
