An equilateral glass prism has a refractive index 1.6 in air. Calculate the angle of minimum deviation of the prism when kept in a medium of refractive index `(4sqrt(2))/(5)`.

Explanation

To solve the problem of finding the angle of minimum deviation (D_m) for an equilateral glass prism in a medium with a given refractive index, we can follow these steps:

### Step 1: Identify the given values
- Refractive index of the prism (μ) = 1.6
- Refractive index of the medium (n) = \( \frac{4\sqrt{2}}{5} \)
- Angle of the prism (A) = 60° (since it is an equilateral prism)

### Step 2: Use the formula for angle of minimum deviation
