MCQ
light of different colours propagates through air
- AWith the velocity of air
- BWith different velocities
- CWith the velocity of sound
- ✓Having the equal velocities
✓
Answer
Correct option: D.
Having the equal velocities
In vacuum, the speed of light is independent of wave length. Thus vacuum (or air) is a non dispersive medium in which all colours travel with the same speed.
