How to Calculate Wave Number?
Wave Number calculator uses Wave Number = (2*pi)/Wavelength to calculate the Wave Number, Wave Number is the spatial frequency of a wave, measured in cycles per unit distance or radians per unit distance. Whereas temporal frequency can be thought of as the number of waves per unit time, wavenumber is the number of waves per unit distance. Wave Number is denoted by k symbol.
