Question

Explain briefly how electromagnetic waves are produced by an oscillating charge. How is the frequency of the em waves produced related to that of the oscillating charge?

Answer 1

An oscillating charge is considered as the accelerating charge. This produces on oscillating electric field in space, which produces an oscillating magnetic field, which again produces oscillating electric field and so on. These oscillating electric and magnetic field thus keep on regenerating each other as the wave propagates through the space.

Thus, the frequency of the electromagnetic waves naturally equals the frequency of oscillation of the charge
