From the figure shown establish a relation between `mu_(1),mu_(2),mu_(3)`.

A

`mu_(3)gtmu_(2)gtmu_(1)`

B

`mu_(3)ltmu_(2)ltmu_(1)`

C

`mu_(2)gtmu_(3),mu_(3)=mu_(1)`

D

`mu_(2)gtmu_(1),mu_(3)=mu_(2)`

Text Solution

Verified by Experts

The correct Answer is:
C
`mu_(1)=mu_(3)` since there is no bending at first surface.
`mu_(3)ltmu_(2)` since the ray bends towards normal as it passes from `mu_(3)` to `mu_(2)` medium.

From the figure shown, establish a relation between mu_1,mu_2,and mu_3

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 relationship between mu_(1) , mu_(2) "and" mu_(3) , it takes one of the four possible paths 'ef' , 'eg' , 'eh' or 'ef' 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 rarr f , 1. mu_(1)gt sqrt(2mu_(2))) , ( Q. e rarr g , 2. mu_(2) gt mu_(1) "and" mu_(2) gt mu_(3)), ( R. e rarr f , 3. mu_(1) = mu_(2)), ( S. e rarr f , 4. mu_(2) lt mu_(1) lt sqrt(2mu_(2)) "and" mu_(2) gt mu_(3)):} Codes : {:( P , Q , R , S) , ((A) 2 , 3 , 1 , 4), ((B) 1 , 2 , 4 , 3) , ((C) 4 , 1 , 2 , 3) , ((D) 2, 3 , 4 , 1):}
