Find the value of the angle of emergence from the prism. Refractive index of the glass is 3 .

Find the value of the angle of emergence from the prism. Refractive index of the glass is 3.

  1. 45°
  2. 30°
  3. 60°
  4. 90°

Solution

No refraction at face AC.

Apply Snell's law at face BC,

we get,

μ1sini=μ2sinr

3sin30°=1×sine

32=sine

⇒e=60°
