If deviation by a prism with small prism...

If deviation by a prism with small prism angle with refractive index 1.6 is `3.6^@`, then prism angle is ….....

A

`7^@`

B

`6^@`

C

`5^@`

D

`8^@`

Text Solution

Verified by Experts

The correct Answer is:
B
`delta=A(n-1)`
`therefore A=(delta)/(n-1)=(3.6)/(1.6-1)=(3.6)/(1.6)=6^@`
