High Quality Content by WIKIPEDIA articles! A wavenumber frequency diagram is a plot displaying the relationship between the wavenumber (spatial frequency) and the frequency (temporal frequency) of certain phenomenas. Usually frequencies are placed on the vertical axis, while wavenumbers are placed on the horizontal axis. In the atmospheric sciences, these plots are a common way to visualize atmospheric waves. In general, the relationship between wavelength , frequency , and the speed of propagation vp is: = vp. Since the wavenumber k, is the inverse of wavelength (k = 1/ ) the previous equati...
High Quality Content by WIKIPEDIA articles! A wavenumber frequency diagram is a plot displaying the relationship between the wavenumber (spatial frequency) and the frequency (temporal frequency) of certain phenomenas. Usually frequencies are placed on the vertical axis, while wavenumbers are placed on the horizontal axis. In the atmospheric sciences, these plots are a common way to visualize atmospheric waves. In general, the relationship between wavelength , frequency , and the speed of propagation vp is: = vp. Since the wavenumber k, is the inverse of wavelength (k = 1/ ) the previous equation can be rewritten as /k=vp Thus the slope of a wavenumber frequency diagram is related to the speed of propagation of the wave. Analyzing this in detail will often yield valuable information on the physical properties of the medium, such as density, composition, etc...
