JEE MAIN - Physics (2024 - 31st January Evening Shift - No. 14)
When unpolarized light is incident at an angle of $$60^{\circ}$$ on a transparent medium from air, the reflected ray is completely polarized. The angle of refraction in the medium is:
$$60^{\circ}$$
$$90^{\circ}$$
$$30^{\circ}$$
$$45^{\circ}$$
Explanation
By Brewster's law
