The critical angle of a medium with respect to air is `45^(@)` . The refractive index of medium is

A

`(sqrt3)/(2)`

B

`(2)/(sqrt3)`

C

`(1)/(sqrt2)`

D

`sqrt2`

Text Solution

Verified by Experts

The correct Answer is:
D
The refractive index of the medium is given by n = `(1)/(sin C) = (1)/(sin 45^(@)) = (1)/((1)/(sqrt2)) = sqrt2`
