-
wavenumber (or wave number), also
known as repetency, is the
spatial frequency of a wave,
measured in
cycles per unit
distance (ordinary
wavenumber)...
- In
meteorological applications, a
zonal wavenumber or
hemispheric wavenumber is the
dimensionless number of
wavelengths ****ing

generalized to (k•r − ωt), by
replacing the
wavenumber k with a wave

- A
wavenumber–frequency
diagram is a plot
displaying the

wavenumber: 1
kayser = 1 wave per centimetre; or, more generally, (
wavenumber in kaysers) = 1/(wavelength in centimetres). The SI unit of
