Question

The property which is not of an electromagnetic wave travelling in free space is that:

Options

• they travel with a speed equal to `1/(sqrt(mu_0 epsilon_0))`.

• they originate from charges moving with uniform speed.

• they are transverse in nature.

• the energy density in electric field is equal to energy density inin magnetic field.

Answer 1

they originate from charges moving with uniform speed.

Explanation:

Electromagnetic waves are generated by accelerating charges, rather than by charges moving at a constant velocity. This is a fundamental characteristic of electromagnetic waves.
