What is the velocity of all electromagnetic waves in a vacuum?
| 1- | The velocity of electromagnetic waves depends upon their amplitude. |
| 2- | The velocity of electromagnetic waves depends upon their wavelength. |
| 3- | The velocity of electromagnetic waves depends upon their frequency. |
| 4- | Electromagnetic waves do not propagate forward; hence, their velocity is zero. |
| 5- | The velocity of electromagnetic waves is nearly equal to 3 |
