Wave number: Know Definition, Formula, Significance, Applications

Wavenumber, as used in spectroscopy and most chemistry fields, is defined as the number of wavelengths per unit distance, typically centimeters (cm ): where λ is the wavelength. It is sometimes called the "spectroscopic wavenumber". It equals the spatial frequency. A wavenumber in inverse cm can be converted to a frequency in GHz by multiplying by 29.9792458 (the speed of light in centimeters per nanosecond). An electromagne… WebA wavenumber is the reciprocal of a wavelength (1/λ); thus, a wavenumber of 1600 cm −1 corresponds to a wavelength of. 1 1600 cm −1 =6.25× 10 −4 cm or 6.25 μ m.
