Question

A linearly polarized light can be obtained from an unpolarized light by which of the following method(s)?

• A. Polarization by Reflection
• B. Polarization by Scattering
• C. Polarization by Refraction
• D. All of the above

Answer 1

The correct option is D All of the above

When an unpolarized light is incident on a transparent medium at Brewster's angle then the reflected light is completely polarized and the refracted light is partially polarized but when we place a number of glass plates parallel to each other at Brewster's angle after successive refraction the refracted light can be plane polarized.

When unpolarized light incident on a medium containing microscopic suspended particles, then the incident light on these particles is scattered in different directions which is partially polarized.

Hence, option $\left(D\right)$ is correct.
