Question

Give the relation b/w wave number wave length​

Answer 1

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.

Answer 2

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.
