1. What do you mean by polarizing angle?

Question

Green light is incident at the Polarizing angle on a certain glass plate as shown in figure.

1. What do you mean by polarizing angle?

2. Indicate the polarization components on the reflected and refracted rays, by arrows and dots.

3. Find the refractive index of glass.

Answer 1

1. The angle of incidence, at which incident light on a transparent medium, become completely plane polarized is known as polarizing angle.

2. 

3. Polarizing angle = 90° – 32° = 58°,

Refractive Index, n = tan 58° = 1.6.
