MCQ
An electromagnetic wave can be produced when the charge is
- Amoving in a circular orbit
- Bmoving with a constant velocity
- Cfalling in an electric field
- ✓Both $(a)$ and $(c)$
✓
Answer
Correct option: D.
Both $(a)$ and $(c)$
An accelerated charge is the source of electromagnetic waves $\text{(EMWs)}$. When the charge is in a circular motion, the direction of its velocity continuously changes and thus it is in accelerated motion and produces $\text{EMWs}$. A charge falling in an electric field is accelerated by the electric force and thus produces $\text{EMWs.}$
