MCQ
The electromagnetic waves travel with a velocity
- AEqual to velocity of sound
- ✓Equal to velocity of light
- CLess than velocity of light
- DNone of these
✓
Answer
Correct option: B.
Equal to velocity of light
b
(b) Velocity of $EM$ waves =$\frac{1}{{\sqrt {{\mu _0}{ \in _0}} }}3 \times {10^8}m/s$ = velocity of light
(b) Velocity of $EM$ waves =$\frac{1}{{\sqrt {{\mu _0}{ \in _0}} }}3 \times {10^8}m/s$ = velocity of light
