Question

the brewster angle when the magnetic field is parallel to the plane of incidence and when the electric field is parallel to the plane of incidence​

Answer 1

Answer:

answer is below

Explanation:

If light strikes an interface so that there is a 90o angle between the reflected and refracted rays, the reflected light will be linearly polarized. The direction of polarization (the way the electric field vectors point)is parallel to the plane of the interface.

The special angle of incidence that produces a 90o angle between the reflected and refracted ray is called the Brewster angle, θp.

A little geometry shows that tan(θp) = n2/n1.
