How are electromagnetic waves produced? What is the source of energy of these waves? Write mathematical expressions for electric and magnetic fields of an electromagnetic wave propagating along the z-axis. Write any two important properties of electromagnetic waves.
Oscillating charges produces the electromagnetic wave. Source of the energy of the wave is the energy of the source which accelerate/oscillate the charge.
Electric field
Magnetic field
Properties
(i) EM waves are transverse in nature
(ii) EM waves can be polarized
