phase velocity in a sentence

Examples

1. :See Dispersion ( optics ) which has a somewhat understandable explanation, in addition to Phase velocity and Group velocity.
2. The phase velocity does not have to exactly equal "'c "'( the universal constant ).
3. Moreover, the velocity that must be exceeded is the phase velocity of light rather than the group velocity of light.
4. However, as stated above, a superluminal phase velocity cannot be used for faster-than-light transmission of information.
5. The phase velocity near the waist exceeds the speed of light in the medium, just as it can in a waveguide.
6. The reverse of the electromagnetic wave, characterized by an antiparallel phase velocity is also an indicator of negative index of refraction.
7. Whereas the first group has a zero-valued phase velocity, the second group has a finite, nonzero phase velocity.
8. Whereas the first group has a zero-valued phase velocity, the second group has a finite, nonzero phase velocity.
9. So the phase velocity formula in the basic Kolsky model is modified by using the highest frequency w h as a reference.
10. One can identify a terrestrial Rossby wave as its phase velocity, marked by its wave crest, always has a westward component.
