A ray of light passes through an equilateral prism (refractive index `1.5`) such that angle of incidence is equal to angle of emergence and the latter is equal to `3//4 th` of the angle of prism. Calculate the angle of deviation.

A

`60^(@)`

B

`30^(@)`

C

`45^(@)`

D

`120^(@)`

Text Solution

Verified by Experts

The correct Answer is:
B
Here, `A = 60^(@) =, mu = 1.5`,
`I = e = 3/4 xx 60^(@) = 45^(@)`
`A + del = i + e`
`:. 60^(@) + delta = 45^(@) + 45^(@) rArr delta = 90^(@) - 60^(@) = 30^(@)`
