What is wave number?

Wavenumber is sometimes called the "spectroscopic wavenumber". It is the reciprocal of the wavelength, λ, or the number of waves per unit length along the direction of propagation. The SI unit is per meter (m^−1), but a commonly used unit is per centimeter (cm^−1).

How to Calculate Wave Number of Electromagnetic Wave?

Wave Number of Electromagnetic Wave calculator uses Wave Number = 1/Wavelength of Light Wave to calculate the Wave Number, The Wave number of electromagnetic wave in most chemistry fields is defined as the number of wavelengths per unit distance. Wave Number is denoted by k symbol.

How to calculate Wave Number of Electromagnetic Wave using this online calculator? To use this online calculator for Wave Number of Electromagnetic Wave, enter Wavelength of Light Wave (λ_lightwave) and hit the calculate button. Here is how the Wave Number of Electromagnetic Wave calculation can be explained with given input values -> 0.047619 = 1/21.

FAQ

What is Wave Number of Electromagnetic Wave?
