If angle of incidence is twice the angle of refraction in a medium of refractive index , then angle of incidence is

Options

  1. A2 ⁻¹ 2
  2. B2 ⁻¹ 2
  3. C2 ⁻¹
  4. D2 ⁻¹

Correct answer

A. 2 ⁻¹ 2

Step-by-step solution

According to Snell's law Refractive index, = i r Given i=2 r = 2 r r or = 2 r r r or ⁻¹ 2 =r i=2 ⁻¹ 2
