The critical angle between a certain transparent medium and air is φ\varphi. A ray of light travelling through air enters the medium at an angle of incidence equal to its polarizing angle θ\theta. Therefore, the angle of refraction is

Options

  1. Atan⁡−1(sin⁡θ)\tan ^{-1}(\sin \theta)
  2. Btan⁡−1(sin⁡φ)\tan ^{-1}(\sin \varphi)
  3. Csin⁡−1(tan⁡θ)\sin ^{-1}(\tan \theta)
  4. Dsin⁡−1(tan⁡φ)\sin ^{-1}(\tan \varphi)

Correct answer

B. tan⁡−1(sin⁡φ)\tan ^{-1}(\sin \varphi)
