A right angled prism of refractive index μ₁ is placed in a rectangular block of refractive index μ₂, which is surrounded by a medium of refractive index μ₃,as shown in the figure. A ray of light 'e' enters the rectangular block at normal incidence. Depending upon the relationships between μ₁, μ₂ and μ₃, it takes one of the four possible paths 'ef','eg','eh' or 'ei'. Match the paths in List I with conditions of refractive indices in List II and select the correct answer using the codes given below the lists : List I List II P. e → f ₁ {2} ₂ Q. e → g ₁ ₂ \; {and} \; ₂ ₃ R. e → h ₁ = ₂ D. e → i ₂ ₃ [JEE Adv 2013 P2]

Correct Answer is : P-2 Q-3 R-4 S-1

List I	List II
P. e → f	$\mu_1 > \sqrt{2} \mu_2$
Q. e → g	$\mu_1 > \mu_2 \; \text{and} \; \mu_2 > \mu_3$
R. e → h	$\mu_1 = \mu_2$
D. e → i	$\mu_2 < \mu_1 < \sqrt{2} \mu_2$ and $\mu_2 > \mu_3$
