phase speed meaning in Hindi

Examples

1. So in deep water the phase speed increases with the wavelength, and with the period.
2. The limiting value of the phase speed for " m " j " 1 directly results.
3. Water waves of different wave lengths travel with different phase speeds, a phenomenon known as frequency dispersion.
4. In deep water the groups travel at a group velocity which is half of the phase speed.
5. For very long waves ( as the zonal wavenumber approaches zero ), the non-dispersive phase speed is approximately:
6. Since this shallow-water phase speed is independent of the wavelength, shallow water waves do not have frequency dispersion.
7. Another property of non-linear waves is that the phase speed of non-linear waves depends on the wave height.
8. This is a nonlinear effect, by which waves of larger amplitude have a different phase speed from small-amplitude waves.
9. Therefore, these waves are non-dispersive ( because the phase speed is not a function of the zonal wavenumber ).
10. First the surface elevation, and thereafter the phase speed, of the cnoidal waves for infinitesimal wave height will be examined.
