Q93 / 100 · BITSAT 2024 (Memory Based Paper 1) · Physics

When a light ray incidents on the surface of a medium, the reflected ray is completely polarized. Then the angle between reflected and refracted rays is

A
$45^{\circ}$
Correct answer
B
$90^{\circ}$
C
$120^{\circ}$
D
$180^{\circ}$

Solution

According to Brewester's law if the reflected ray is completely polarized, then the reflected and refracted ray is perpendicular to each other. Thus, $\theta=90^{\circ}$

Hence, the correct answer is option: 'B'.
