Select the correct statement from the following :

Options

  1. AElectromagnetic waves cannot travel in vacuum.
  2. BElectromagnetic waves are longitudinal waves.
  3. CElectromagnetic waves are produced by charges moving with uniform velocity.
  4. 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.
