A light ray falls on a glass surface of refractive index 3, at an angle 60°. The angle between the refracted and reflected rays would be:
  1. 60°
  2. 90°
  3. 120°
  4. 30°

Solution

From Snell's law,

μ1sini=μ2sinr

1×sin60°=3sinr

  r=30°

Angle between the refracted say and reflected say is

θ=180°-i+r=90°
