Amplitude refers to the height or depth of a wave signal such as sound or light, which correlates with perceived loudness in sound waves and brightness in light waves.
The number of complete wavelengths that pass a point in a given time. For example, frequency determines pitch in sound waves.
The distance between successive crests of a wave.
Perceived frequency of a sound; high-frequency sounds are high-pitched and low-frequency sounds are low-pitched.
