Two parallel light rays are incident at ...

Two parallel light rays are incident at one surface of a prism of refractive index `1.5`. What is the angle between the rays as they emerge? `sin^-1(0.75)=48.5^@`

A

`19^@`

B

`37^@`

C

`45^@`

D

`30^@`

Text Solution

Verified by Experts

The correct Answer is:
B

As solved in previous problem
`=2(sin^-1(0.75)-30^@)`
`=2(48.5^@-30^@)=37^@`
