Question : 17

Total: 60

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	μ1>√2μ2
Q. e → g	μ1>μ2‌and‌μ2>μ3
R. e → h	μ1=μ2
D. e → i	μ2<μ1<√2μ2 and μ2>μ3

P-2 Q-3 R-1 S-4
P-1 Q-2 R-4 S-3
P-4 Q-1 R-2 S-3
P-2 Q-3 R-4 S-1
