A small angle prism (μ = 1.62) gives a deviation of 4.8°. The angle of prism is (Assume min. deviation)

A

5°

B

6.36°

C

3°

D

7.74°

Correct Answer

Option D

Detailed Explanation

Using the formula δ = (μ - 1)A, where δ is the deviation and A is the angle of the prism, we can calculate A. Given δ = 4.8° and μ = 1.62, we find A = 7.74°.
