Question

What is polarizing angle? Give two uses of a Polaroid.

Answer 1

Polarizing Angle is an angle of incidence at which light with a particular polarization is perfectly transmitted through transparent dielectric surface without any reflection.

The two uses of Polaroids are:

1)  They can be used to eliminate the headlight glare in motor cars.
2) They can be used to improve color contrasts in old oil paintings.

Answer 2

The polarization angle is known as the Brewster's angle. It is an angle of incidence at which light with a particular polarization is transmitted perfectly through a transparent dielectric surface without any reflection.

Uses of Polaroids:

1. They are used as polarizing sun glasses.

2. Polaroid films are used in the production of three dimensional moving pictures.
