Polarised light can be produced by scattering through $\frac{\pi}{2}$ in the Earth's atmosphere.

Vedclass · Answer

(C) Option $C$ is correct. When sunlight enters the Earth's atmosphere,the atoms and molecules scatter the light. For light scattered at an angle of $\frac{\pi}{2}$ ($90$ degrees) relative to the incident beam,the scattered light is found to be plane-polarised. Option $A$ is incorrect because plane-polarised light remains plane-polarised after passing through a polaroid (its intensity may change). Option $B$ is incorrect because the refracted light at Brewster's angle is partially polarised,not fully linearly polarised. Option $D$ is incorrect because natural sunlight is unpolarised.
