| 11. | The phase velocity drops smoothly while the group velocity drops somewhat precipitously towards a minimum.
|
| 12. | The mirrors do not require matching the phase velocities of the input and output waves.
|
| 13. | In dispersive media the phase velocity is not necessarily the same as the group velocity.
|
| 14. | Since wave phase velocity is given by
|
| 15. | The superluminal phase velocity does not violate special relativity, because phase propagation carries no energy.
|
| 16. | In this case the phase velocity is
|
| 17. | These special disturbances propagate through a material at a speed slower than called the phase velocity.
|
| 18. | The phase velocity is given as:
|
| 19. | Your response leaves me wondering, though, are photons always traveling at the phase velocity?
|
| 20. | The phase velocity varies with frequency.
