A prism is made of glass of refractive index 1.5. If the angle of minimum deviation is equal to the refracting angle of the prism, calculate the angle of the prism.

Explanation

To solve the problem, we need to find the angle of the prism (A) given that the refractive index (μ) of the glass is 1.5 and the angle of minimum deviation (Δm) is equal to the angle of the prism (A).

### Step-by-Step Solution:

1. **Understanding the Relationship**:
We know that at the angle of minimum deviation, the angle of minimum deviation (Δm) is equal to the angle of the prism (A). Therefore, we can write:
\[
A = Δm
