If critical angle for total internal ref...

If critical angle for total internal reflection in diamond is `24.5^@`, then refractive index of diamond is ...... [Take sin `24.5^@` = 0.4147]

A

1.41

B

1.51

C

2.1

D

2.41

Text Solution

Verified by Experts

The correct Answer is:
A, B, D
`C=24.5^@` sin(24.5)=0.4147
Refractive index n = `(1)/(sinC)`
`thereforen=(1)/(0.4147)`
`thereforen=2.41`
