Wave Optics Question 12

Question 12 - 2024 (31 Jan Shift 2)

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

(1) $30^{\circ}$

(2) $60^{\circ}$

(3) $90^{\circ}$

(4) $45^{0}$

Show Answer

Answer: (1)

Solution:

By Brewster’s law

At complete reflection refracted ray and reflected ray are perpendicular.
