# Wave number

In the physical sciences, the wavenumber (also wave number) is the spatial frequency of a wave, either in cycles per unit distance or radians per unit distance. Topics › Computer Science › ElectronicsCachadLiknandeÖversätt den här sidanThe term wave number refers to the number of complete wave cycles of an electromagnetic field (EM field) that exist in one meter (m) of linear space. Wavenumber, sometimes called the propagation number, is in broad terms a measure of spatial scale. It can be thought of as a spatial analog . Physics – Mechanics: Mechanical Waves (of 21) The. Wave number, a unit of frequency in atomic, molecular, and nuclear spectroscopy equal to the true frequency divided by the speed of light and . Often in Chemistry one will use the reciprocal of the wavelength in centimeters as a measure of the frequency of radiation. In a traveling plane wave, wavenumber is the spatial equivalent of frequency.

If you stopped time, the wavenumber tells you how many radians there are per unit . Böjningar av wavenumber, Singular, Plural. There are unfortunately two different definitions of the wavenumber. French (197 p. 214) uses the definition .
