Question

What is meant by transverse nature of electromagnetic wave? Draw a diagram showing the propagation of an electromagnetic wave along the X direction, indicating clearly the directions of the oscillating electric and magnetic field.

Answer 1

Transverse nature of electromagnetic waves means the electric and magnetic fields in an electromagnetic wave are perpendicular to each other and to the direction of propagation. Below, is the diagram showing the propagation of an electromagnetic wave along x-direction. ... Plane EM wave travels in vacuum along z-direction.
