Marks: +1, -0
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    List-II
 (P)  If n=2 and α=180∘ , then all the possible values of θ0 will be  (1)  30° and 0°
 (Q)  If n=√3 and α=180∘, then all the possible values of θ0 will be  (2)  60° and 0°
 (R)  If n=√3 and α=180∘, then all the possible values of Ï•0 will be  (3)  45° and 0°
 (S)  If n=√2 and θ0=45∘ , then all the possible values of α will be  (4)  150°
     (5)  0°
