A light ray falls on a glass surface of refractive index 3\sqrt{3}, at an angle 60°60 °. The angle between the refracted and reflected rays would be:A light ray falls on a glass surface of refractive index 3 , at an angle 60 ° . The angle between the refracted and

Options

  1. A60°60 °
  2. B90°90 °
  3. C120°120 °
  4. D30°30 °

Correct answer

B. 90°90 °

Step-by-step solution

A light ray falls on a glass surface of refractive index 3 , at an angle 60 ° . The angle between the refracted and

From Snell's law,

μ1sini=μ2sinr{\mu}_{1}sini = {\mu}_{2}sinr

⇒1×sin⁡60°=3sinr⇒ 1 \times \sin 60 ° = \sqrt{3}sinr

⇒r=30°⇒ r = 30 °

Angle between the refracted say and reflected say is

θ=180°−(i+r)=90°\theta = 180 ° - \left(i + r\right) = 90 °
