Out of the following options which one can be used to produce a propagating electromagnetic wave?
A charge moving at constant velocity
A stationary charge
A chargeless particle
An accelerating charge
Total radiant Flux (Power) -
q = Charge
= Acceleration of particle
c = Speed of light in vacuum
- wherein
The accelerated charge particle produce EM wave. P is total radiant flux emitted by charge at any instant.
Electromagnetic wave can be produced by an accelerating charge.
