Refracting angle o f a prism `A=60^@` and its refractive index is `n=3//2`. What is angle of incidence i to get minimum deviation. Also, find the minimum deviation. Assume the surrounding medium to be air `(n=1)`.

Explanation

To solve the problem, we will follow these steps:

### Step 1: Understand the given data
We are given:
- Refracting angle of the prism, \( A = 60^\circ \)
- Refractive index of the prism, \( n = \frac{3}{2} \)
- Refractive index of air, \( n_{air} = 1 \)
