A ray of light is incident at `60^(@)` on one face of a prism of angle `30^(@)` and the emergent ray makes `30^(@)` with the incident ray. The refractive index of the prism is

A

`sqrt(3)/4`

B

`sqrt(3)/2`

C

`sqrt(3)`

D

`2sqrt(3)`

Text Solution

Verified by Experts

The correct Answer is:
C
`d=i_(1) + i_(2)-A,impliesi_(2)=0,:. R_(2)=o,r_(1)=A`
`mu=(Sini_(1))/(Sinr_(1))`
