Waves are associated with matter only:
1. | When it is stationary. |
2. | When it is in motion with the velocity of light only. |
3. | When it is in motion with any velocity. |
4. | None of the above. |
1. | Equal to \(c\), the speed of light in vacuum. |
2. | Greater than \(c\). |
3. | Less than \(c\). |
4. | Tending to infinity. |
