Question

A plane polarized electrodynamics wave travelling in a dielectric medium of refractive index n is reflected at normal incidence from the surface of a conductor find the phase change undergone by its electric vector if the refractive index of the conductor is n2=n(1+ip)

Answer 1

A plane polarized electrodynamics wave travelling in a dielectric medium of refractive index n is reflected at normal incidence from the surface of a conductor. The phase change undergone by its electric vector if the refractive index of the conductor is n2=n(1+ip) is as follows:

Explanation:

If two forces acts in opposite direction of an object then one force will be negative and the object will move in the direction opposite to greater force.

And when equal force is being applied to an object from both the directions then the net force will become zero which indicates or means that the object will not move from it's place.
