In physics, the wavelength of a sinusoidal wave is the spatial period of the waveâthe distance over which the wave's shape repeats,[1] and thus the inverse of the spatial frequency.
If you are curious about what optical density and wavelength mean, this will give you a good idea: 1  Wavelength is the length of a wave from a given point on the wave to the next time that point repeats. 2  Wavelength corresponds inversely with frequency.
