Wavelength
[[/a>|/a>
]]
In general, the mean distance between maximums (or minimums) of a roughly
periodic
pattern. Specifically, the least distance between particles moving in the same
phase of oscillation
in a wave
disturbance.

The wavelength is measured along the direction of propagation of the
wave, usually from the midpoint of a crest (or trough) to the midpoint of the
next adjoining crest (or trough). It is related to frequency f and phase speed
v by λ = v / f , where λ is wavelength. The reciprocal of wavelength is
the wave
number.
