A ray of light passes through an equilateral prism in such a way that the angle of incidence is equal to the angle of emergence and each of these angles is `3//4`th the angle of the prism. Determine the (i) angle of deviation and (ii) the refractive index of the prism.

Explanation

To solve the problem step by step, we will follow the given information and apply the relevant physics concepts.

### Step 1: Understand the Problem
We have an equilateral prism where:
- The angle of incidence (i) is equal to the angle of emergence (e).
- Both angles are \( \frac{3}{4} \) of the angle of the prism.

### Step 2: Determine the Angle of the Prism
