Wavenumber
In the physical sciences, the wavenumber (also wave number or repetency) 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.
Wavenumber - Wikipedia Jump to content From Wikipedia, the free encyclopedia Spatial frequency of a wave Diagram illustrating the relationship between the wavenumber and the other properties of harmonic waves In the physical sciences , the wavenumber (or wave number ), also known as repetency , [ 1 ] is the spatial frequency of a wave . Ordinary wavenumber is defined as the number of wave cycles divided by length; it is a physical quantity with dimension of reciprocal length , expressed in SI units of cycles per metre or reciprocal metre (m −1 ). Angular wavenumber , defined as the wave phase
