wave number

[′wāv ‚nəm·bər]
(physics)
The reciprocal of the wavelength of a wave, or sometimes 2π divided by the wavelength. Also known as reciprocal wavelength.

Wave Number

 

a quantity related to the wavelength λ by the ratio k = 2π/λ (the number of waves in a length of 2 π). In spectroscopy the reciprocal of the wavelength (I/λ.) is often called the wave number.

wave number

The reciprocal of a wavelength (i.e., 1/λ or 2/λ, where λ is the wavelength).
