Question

Monochromatic light is incident on a glass prism of angle A. If the refractive index of the material of the prism is μ a ray incident at an angle θ, on the face AB would get transmitted through the face AC of the prism provide

Answer 1

Correct Option (a)

Explanation:

The ray will get transmitted. through face AC if AC if i_AC < i_C Consider the ray diagram as shown below

A ray of light incident on face AB at an angle θ

r₁ = Angle of refraction on face AB

r₂ = Angie of incidence at face AC

For transmission of light through face AC

Now, applying Snell's law at the face AB
