A light ray is incident on the surface of a sphere of refractive index n at an angle of incidence θ₀. The ray partially refracts into the sphere with angle of refraction ϕ₀ and then partly reflects from the back surface. The reflected ray then emerges out of the sphere after a partial refraction. The total angle of deviation of the emergent ray with respect to the incident ray is α. Match the quantities mentioned in List-I with their values in List-II and choose the correct option. List-I: (P) If n = 2 and α = 180°, then all possible values of θ₀; (Q) If n = √3 and α = 180°, then all possible values of θ₀; (R) If n = √3 and α = 180°, then all possible values of ϕ₀; (S) If n = √2 and θ₀ = 45°, then all possible values of α. List-II: (1) 30° and 0°, (2) 60° and 0°, (3) 45° and 0°, (4) 150°, (5) 0°.
