| 21. | In materials with relative permittivity,, and relative permeability,, the phase velocity of light becomes
|
| 22. | There are two velocities that are associated with waves, the phase velocity and the group velocity.
|
| 23. | Each of these components travels with its own phase velocity, in accordance with the dispersion relation.
|
| 24. | Because the phase velocity of the magnetosonic mode is almost always larger than " v"
|
| 25. | The red dot moves with the phase velocity, and the green dots propagate with the group velocity.
|
| 26. | He showed that the phase velocity could be made anti-parallel to the direction of Poynting vector.
|
| 27. | Such a behaviour is enabled by the capability of double-negative materials to yield negative phase velocity.
|
| 28. | The time-varying amplitude does not propagate at the phase velocity but rather at the group velocity.
|
| 29. | The phase velocity of light is not generally equal to c ( the vacuum speed of light ).
|
| 30. | Usually, such reports deal with a phase velocity or group velocity faster than the vacuum velocity of light.
