The wavelength is the spatial period of a periodic wave, in other words the distance over which the wave's shape repeats.
It is usually denoted by the Greek letter .

In linear media, the wavelength of a sinusoidal waveform traveling at constant speed is given by:

Where is the temporal frequency of the wave.
