Answer:
Wave number, a unit of frequency in atomic, molecular, and nuclear spectroscopy equal to the true frequency divided by the speed of light and thus equal to the number of waves in a unit distance.

Explanation:
Wavelength( λ) (cm): The distance over which the wave's shape repeats.
or : The spatial period of a periodic wave.
Wavenumber ( ʋ )(cm-1): The spatial frequency of a wave, measured in cycles per unit distance.
Relation between Wavelength and Wavenumber is according to the following equation:
ʋ = 1/λ
Wavenumber( ʋ ) is used in spectroscopy such as FTIR.
