The source of electromagnetic waves can be a charge.

A

moving with a constant velocity

B

moving in a circular orbit

C

at rest

D

falling in an electric field

Text Solution

Verified by Experts

The correct Answer is:
(b,d)
An em wave can be produced by accelerated or oscillating charge. In option (b) and (d), the charge is
in accelerated state, hence will be a source of em wave.
