An equilateral glass prism is made of a material of refractive index 1.500. Find its angle of minimum deviation.

Explanation

To find the angle of minimum deviation (Δm) for an equilateral glass prism with a refractive index (μ) of 1.5, we can follow these steps:

### Step 1: Identify the angle of the prism
For an equilateral prism, the angle (A) is 60 degrees.

### Step 2: Use the prism formula
The formula relating the refractive index (μ), the angle of the prism (A), and the angle of minimum deviation (Δm) is given by:
\[
