Also the phase speed is independent of the trochoidal wave's amplitude, unlike other nonlinear wave-theories ( like those of the Stokes wave and cnoidal wave ) and observations.
32.
The phase speed ( also called the celerity ) of a surface gravity wave is for pure periodic wave motion of small-amplitude waves well approximated by
33.
When a charged particle moves faster than the phase speed of light in a medium, electrons interacting with the particle can emit coherent photons while conserving energy and momentum.
34.
On the other hand, the phase speed of the linearised KdV equation changes sign for short waves with " ?h " > \ scriptstyle \ sqrt { 6 }.
35.
Relative phase speed increase of cnoidal wave solutions for the Korteweg de Vries equation as a function of 1 " " m ", with " m " the elliptic parameter.
36.
If the wavelength is very long compared to the water depth, the phase speed ( by taking the limit of when the wavelength approaches infinity ) can be approximated by
37.
On the other hand, for very short wavelengths, surface tension plays an important role and the phase speed of these gravity-capillary waves can ( in deep water ) be approximated by
38.
The phase speed is identical to that of coastal Kelvin waves, indicating that the equatorial Kelvin waves propagate toward the east without dispersion ( as if the earth were a non-rotating planet ).
39.
The second day is a four-phase speed and endurance test that includes a " roads and tracks " element of relaxed travel across a field, a steeplechase and a grueling cross-country jumping segment.
40.
The primitive equations are identical to those used to develop the coastal Kelvin wave phase speed solution ( U-momentum, V-momentum, and continuity equations ) and the motion is unidirectional and parallel to the equator.
