An electromagnetic wave can be produced,...

An electromagnetic wave can be produced, when charge is

A

moving with a constant velocity

B

moving in a circular orbit

C

falling in an electric field

D

both (b) and (c)

Text Solution

Verified by Experts

The correct Answer is:
D
An electromagnetic wave can be produced by accelerated or oscillating charge. In options (b) and (c), the charge is in accelerated state, hence it will be a source of electromagnetic waves.
