Select the correct statement from the following :
Select the correct statement from the following :
Options
- AElectromagnetic waves cannot travel in vacuum.
- BElectromagnetic waves are longitudinal waves.
- CElectromagnetic waves are produced by charges moving with uniform velocity.
- DElectromagnetic waves carry both energy and momentum as they propagate through space.
Correct answer
D. Electromagnetic waves carry both energy and momentum as they propagate through space.
Step-by-step solution
Electromagnetic waves do not required any medium to propagate. They can travel in vacuum. They are transverse in nature like light. They carry both energy and momentum.
A changing electric field produces a changing magnetic field and vice-versa. Which gives rise to a transverse wave known as electromagnetic wave.
