## Top best answers to the question «How to calculate wave number»

Wave number is **expressed in reciprocal meters (m ^{-}^{1})**. The wave number for an EM field is equal to 2 pi divided by the wavelength in meters. (In some references, it is defined as the reciprocal of the wavelength in meters; in still others, it is defined as the reciprocal of the wavelength in centimeters.)
