Physics Question on Electromagnetic waves
Select the correct statement from the following
A
Electromagnetic waves cannot travel in vacuum
B
Electromagnetic waves are longitudinal waves
C
Electromagnetic waves are produced by charges moving with uniform velocity
D
Electromagnetic waves carry both energy and momentum as they propagate through space
Answer
Electromagnetic waves carry both energy and momentum as they propagate through space
Explanation
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
