Question

The refractive index of the material of a prism is \(n=1.6\). Find the ratio of the angle of the prism to the angle of minimum deviation.

• A. \(3:2\)
• B. \(5:3\)
• C. \(2:1\)
• D. \(4:3\)

Hint:

For a thin prism, \[ \delta=(n-1)A \] Always remember that deviation is directly proportional to prism angle and refractive index excess \((n-1)\).

Answer 1

The Correct Option is D
