A ray of light is incident on the surface of a glass plate of refractive index 1.6 at polarzing angle. Calculate the angles of reflection and refraction.

A narrow monochromatic beam of light of intensity 1 is incident on a glass plate as shown in figure Another identical glass plate is kept close to the first one and parallel to it. Each glass plate reflects 25% of the light incident on it and transmits intensities in the interference pattern formed by two beams obtained after one reflection at each plate.
