- These phase speeds are in full agreement with the result obtained by directly searching for sine-wave solutions of the linearised KdV and BBM equations.
- In a " dispersive " medium, the phase speed itself depends upon the frequency of the wave, making the relationship between wavelength and frequency nonlinear.
- On the other hand, for a given ( fixed ) wavelength, gravity waves in deeper water have a larger phase speed than in shallower water.
- While the phase velocity is a vector and has an associated direction, celerity or phase speed refer only to the magnitude of the phase velocity.
- The wavelength of capillary waves in water is typically less than a few centimeters, with a phase speed in excess of 0.2 meter / second.
- Surface gravity waves on a fluid are dispersive waves exhibiting frequency dispersion meaning that each wavenumber has its own frequency and phase speed.
- For " ? " equal to zero, the Camassa Holm equation has no frequency dispersion moreover, the linear phase speed is zero for this case.
- In the case of electromagnetic radiation such as light in free space, the phase speed is the speed of light, about 3?0 8 m / s.
- Showing a 3.8 % increase due to the effect of nonlinear amplitude dispersion, which wins in this case from the reduction of phase speed by frequency dispersion.
- Where " v " is called the phase speed ( magnitude of the phase velocity ) of the wave and " f " is the wave's frequency.
- 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.
- 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
- 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.
- On the other hand, the phase speed of the linearised KdV equation changes sign for short waves with " ?h " > \ scriptstyle \ sqrt { 6 }.
- 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.
- 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
- 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
- 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 ).
- 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.
- 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.
