As is evident from these equations, the linearised BBM equation has a positive phase speed for all " ?h ".
12.
According to linear theory for waves forced by gravity, the phase speed depends on the wavelength and the water depth.
13.
In this formulation the phase speed is a function of wave height " H " and parameter " m ".
14.
This implies that the limiting values of the phase speed " c " and minimum elevelation " ? 2 " become:
15.
For lossy media, more intricate models need to be applied in order to take into account frequency-dependent attenuation and phase speed.
16.
For engineering use, the fifth-order formulations of Fenton are convenient, applicable to both Stokes second definition of phase speed ( celerity ).
17.
The most generally familiar sort of breaking wave is the breaking of plasmas, when the particle velocities exceed the wave's phase speed.
18.
The phase speed gives you the speed at which a point of constant phase of the wave will travel for a discrete frequency.
19.
A sinusoidal wave, of small surface-elevation amplitude and with a constant wavelength, propagates with the phase velocity, also called celerity or phase speed.
20.
Since the phase speed satisfies " c p = ? / T = ?f ", wavelength and period ( or frequency ) are related.
