Deviation of `5^@` is observed from a prism whose angle is small and whose refractive index is 1.5. The angle of prism is

A

`7.5^@`

B

`10^@`

C

`5^@`

D

`3.3^@`

Text Solution

Verified by Experts

The correct Answer is:
B
According to the relation
`delta = (mu - 1) A implies 5 = (mu - 1) A`
`5 = (1.5 - 1) A`
`A = 10^@`
