NEETPhysicsGeometrical OpticsMCQ+4 / −1

A light ray falls on a glass surface of refractive index 3\sqrt33​, at an angle 60∘^\circ∘. The angle between the refracted and reflected rays would be

  1. A
    30∘^\circ∘
  2. B
    60∘^\circ∘
  3. C
    90∘^\circ∘
  4. D
    120∘^\circ∘

Correct answer: C

Given i = 60$^\circ$ and $\mu$ = $\sqrt3$

$\Rightarrow$ Here, angle of incidence $\Rightarrow$ i = tan$-$1 ($\mu$)

Hence, reflected and refracted rays would be perpendicular to each other.
