the height of a wave measured from rest to the top of the crest or bottom of the trough of the wave; often used to describe volume of sound or intensity of light

 a measurable quantity that describes how much change can occur within a system

the number of waves that pass a given point in a specified amount of time (usually 1 second), measured in hertz (Hz); the pitch of a sound or the color of light

a type of wave in which the particles oscillate perpendicular to the direction in which the energy propagates

a disturbance or variation that transfers energy progressively from point to point with or without a medium, without transferring matter

distance between the same point on two successive waves; distance from crest to crest or trough to trough for two consecutive waves
