Light traveling from a transparent medium to air undergoes that internal reflection at an angle of incident of `45^(@)`. Then refractive index of the medium may be

A

1.5

B

1.3

C

1.1

D

`(1)/(sqrt(2))`

Text Solution

Verified by Experts

`mu = (1)/(sin i_(c)) = (1)/(sin 45^(@)) = sqrt(2) = 1.414 approx 1.5`
