Question

The source of electromagnetic wave can be a charge. (A) Moving with a constant velocity (B) Moving in a circular orbit (C) At rest (D) Moving parallel to the magnetic field

Tardigrade Admin · Accepted Answer

Charges moving in a circular orbit undergo centripetal acceleration hence emit em waves. Or when electron jumps from one higher stationary orbit to another lower stationary orbit emits em radiation.

Q. The source of electromagnetic wave can be a charge.

Moving with a constant velocity

Moving in a circular orbit

At rest

Moving parallel to the magnetic field

Charges moving in a circular orbit undergo centripetal acceleration hence emit em waves. Or when electron jumps from one higher stationary orbit to another lower stationary orbit emits em radiation.
