A thin prism of `2^(@)` angle gives a deviation of `1^(@)`. What is the value of refractive index of the material of the prism.

Explanation

To find the refractive index of the material of a thin prism given its angle and the deviation, we can use the formula for the refractive index (μ) in terms of the angle of the prism (A) and the angle of deviation (D).

### Step-by-Step Solution:

1. **Identify the Given Values:**
- Angle of the prism (A) = 2 degrees
- Angle of deviation (D) = 1 degree
