Question

(a) How are electromagnetic waves produced?(b) How do you convince yourself that electromagnetic waves carry energy and momentum?

Answer 1

(a) The creation of all electromagnetic waves begins with an oscillating charged particle, which creates oscillating electric and magnetic fields.

(b) Let’s assume a plane is perpendicular to the direction of propagation of wave. If we will keep an electric charge incident on plane, it will be set in motion by electric and magnetic field of electromagnetic waves. So, this proves that how electromagnetic waves carry energy and momentum.
