Question

thr refractive index of a medium is root 3 at what angle of incidence and angle between reflected and refracted ray will be perpendicular to each other?

Answer 1

Answer:

The incidence angle is 60°.

Explanation:

Given that,

Refractive index $\mu=\sqrt{3}$

The light ray strikes on the surface and makes the angle between the incidence ray and normal ray is called incidence angle.

We know that,

$tan\ i_{p}=\mu$

$tan\ i_{p} =\sqrt{3}$

$i_{p}=tan^{-1}\sqrt{3}$

$i_{p}= 60^{\circ}$

Hence, The incidence angle is 60°.
