The relation between angle of incidence `i`, angle of prism `A` and angle of minimum deviation for a triangular prism is.

Explanation

To find the relation between the angle of incidence \( i \), the angle of prism \( A \), and the angle of minimum deviation \( \Delta_M \) for a triangular prism, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Geometry of the Prism**:
- Consider a triangular prism with an apex angle \( A \).
- When light enters the prism, it makes an angle of incidence \( i \) at the first face and exits at the second face.
