(b) State two applications of plane polarized light.

Answer

Answer Details

(a) Waves (other than light) that can be plane polarized

Only transverse waves can be polarized. Examples apart from light are:

Radio waves (and microwaves) - transverse electromagnetic waves.
Transverse mechanical waves on a stretched rope or string (X-rays are also acceptable).

(b) Two applications of plane polarized light

In polaroid sunglasses and camera filters to cut down glare from reflected light.
In liquid-crystal displays (LCDs); also used in stress analysis of transparent models (photoelasticity) and in the polarimeter to measure sugar concentration.
