Solution and Explanation
Plane polarized light consists of waves oscillating in a single plane perpendicular to the direction of propagation.
Obtaining polarized light by refraction:When unpolarized light is incident at Brewster's angle on a transparent medium, the reflected light becomes plane polarized.
Uses of polaroid:- Reducing glare in sunglasses and cameras.
- Enhancing contrast in liquid crystal displays (LCDs).
