Home / Entry / Amplitude

Amplitude

The amplitude of a wave is a measurement of the distance from the top of a crest through the centre line  (the still position, zero-point, mid-point) to the bottom of a trough.

  • In the case of an electromagnetic wave, amplitude corresponds with the perception of the intensity of light and the brightness of colour perceived by an observer.
