Wavelength to Wavenumber Conversion Calculator

Wavelength and wavenumber are both measures of the properties of a wave, but they represent different aspects of the wave.
Wavelength (λ) refers to the distance between two consecutive peaks of a wave. It is typically measured in units of length, such as meters. Wavelength determines the color of light, the pitch of sound, and other characteristics of the wave.
Wavenumber (ν) is the number of wave cycles that pass a fixed point per unit length. It is usually measured in reciprocal units of distance, such as per meter (m^-1). Wavenumber is often used in spectroscopy to describe the energy of a photon, which is proportional to the frequency of the electromagnetic wave.
A wavenumber for a given wave is inversely proportional to its wavelength. A shorter wavelength will have a longer wavenumber with more complete wave cycles and vice versa.
