A small angled prism `(mu = 1.62)` gives a deviation of `4.8`. Calculate the angle of prism.

A

`5^(@)`

B

`6.36^(@)`

C

`3^(@)`

D

`7.74^(@)`

Text Solution

Verified by Experts

The correct Answer is:
D
Here, `mu = 1.62, del = 4.8^(@)`
`del = (mu-1) A` or `A = (delta)/((mu-1))= (4.8)/((1.62 - 1)) = 7.74^(@)`
