A ray of light travelling in a transparent medium falls on a surface separating the medium from air at an angle of incidence of `45^(@)`. The ray undergoes total internal reflection. If n is the refractive index of the medium with respect to air, select the possible value of n from the following.

A

1.2

B

`4//3`

C

1.4

D

1.5

We have, `sinigtsintheta_(c)`
`therefore sin45^(@)gt(1)/(n)or(1)/(sqrt(2))gt(1)/(n)`
`therefore ngtsqrt(2)orngt1.414`
