Consider the situation as shown in figure. The point O is the centre. The light ray forms an angle of `60^@` with the horizontal and each mirror makes an angle `60^@` with the normal. The value of refractive index of that spherical portion so that light ray retraces its path is

A

`sqrt2`

B

`2/sqrt3`

C

43526

D

`sqrt3`

Text Solution

Verified by Experts

The correct Answer is:
D
(d) Refractive index,`mu=(sin60^(@))/(sin30^(@))=(sqrt3//2)/(1//2)=sqrt3`
