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.

Answer 2

Q) what is the wave number ?

ANSWER:-

In fluid dynamics , dispersion of water waves generally refer to frequency dispersion which means that waves of different wavelength travel at different phase speed .
