Question

When an electromagnetic wave is incident from medium 1 to medium 2 brewster angle uis?

Answer 2

Answer:

There is more to be said about the complex vector amplitudes and . We introduce a right-

handed set of orthogonal unit vectors as shown in where we take to be

the propagation direction of the plane wave. In general, the electric field amplitude can be

written as

where the amplitudes and are arbitrary complex numbers. The two plane waves with

(if the index of refraction is real, and have the same phase) are said to be linearly

polarized with polarization vectors and . Thus the most general homogeneous plane wave

propagating in the direction is expressed as the superposition of two independent

plane waves of linear polarization:

It is convenient to express the complex components in polar form. Let

Then, for example,

that is, is the phase of the -field component in the -direction. It is no restriction to let

Explanation:

Brewster's angle, or the polarizing angle, is defined as an angle at which an incident beam of unpolarized light is reflected after complete polarization. The incident light with an electric field parallel to the plane of incidence usually has a zero reflection coefficient at a particular angle between 0 and 90°.
