QS Study

According to Maxwell, an accelerated charge is a source of electromagnetic radiation.

In an electromagnetic wave, electric and magnetic field vectors are at right angles to each other and both are at right angles to the direction of propagation.

They possess the wave character and propagate through free space without any material medium. These waves are transverse in nature.
