A light ray is incident on the surface of a sphere of refractive index $$n$$ at an angle of incidence $$\theta_0$$. The ray partially refracts into the sphere with angle of refraction $$\phi_0$$ 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 $$\alpha$$. Match the quantities mentioned in List-I with their values in List-II and choose the correct option.

(P)	If $$n = 2$$ and $$\alpha = 180°$$, then all the possible values of $$\theta_0$$ will be	(1)	$$30°$$ and $$0°$$
(Q)	If $$n = \sqrt{3}$$ and $$\alpha = 180°$$, then all the possible values of $$\theta_0$$ will be	(2)	$$60°$$ and $$0°$$
(R)	If $$n = \sqrt{3}$$ and $$\alpha = 180°$$, then all the possible values of $$\phi_0$$ will be	(3)	$$45°$$ and $$0°$$
(S)	If $$n = \sqrt{2}$$ and $$\theta_0 = 45°$$, then all the possible values of $$\alpha$$ will be	(4)	$$150°$$
		(5)	$$0°$$
