| 1. | :All the electromagnetic waves travel at the velocity of light in vacuum.
|
| 2. | Couple that with the velocity of light and you can measure distance.
|
| 3. | They travel in straight lines at exactly the velocity of light.
|
| 4. | Till now Science havent managed to defeat the velocity of Light.
|
| 5. | The velocity of light in the glass is then given by:
|
| 6. | Slow light refers to a very low group velocity of light.
|
| 7. | It has no mass and has the velocity of light.
|
| 8. | In materials with relative permittivity,, and relative permeability,, the phase velocity of light becomes
|
| 9. | Apachite is an anisotropic mineral, so the velocity of light varies for this mineral.
|
| 10. | Energy equals mass times the velocity of light squared.
