A right angled prism of refractive index \mu_1 is placed in a rectangular block of refractive index \mu_2 , which is surrounded by a medium of refractive index \mu_3, as shown in the figure. A ray of light ‘e’ enters the rectangular block at normal incidence.Depending upon the relationships between \mu_1 , \mu_2 and \mu_3 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 thecorrect answer using the codes given below the lists : Column- I Column –II A) e → f p) \mu_1 > \sqrt2\mu_2 B) e → g q) \mu_2 > \mu_1 and \mu_2 > \mu_2 C) e → h r) \mu_1 = \mu_2 D) e → i s) \mu_2 \mu_2

Correct Answer is : A → q ; B → r ; C → s ; D → p

A → r; B → s ; C → p ; D → q

A → s ; B → p ; C → q ; D → r

A → p ; B → q ; C → r ; D → s

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 thecorrect answer using the codes given below the lists :

Column- I	Column –II
A) e → f	p) µ1 > √2µ2
B) e → g	q) µ2 > µ1 and µ2 > µ2
C) e → h	r) µ1 = µ2
D) e → i	s) µ2 < µ1 < √2µ2 and µ2 > µ2

A → r; B → s ; C → p ; D → q
A → s ; B → p ; C → q ; D → r
A → p ; B → q ; C → r ; D → s
A → q ; B → r ; C → s ; D → p
