A ray of light passing through an equilateral triangular glass prism from air undergoes minimum deviation when angle of incidence is `3//4` th of the angle of prism. Calculate the speed of light in the prism.

Explanation

To solve the problem of finding the speed of light in an equilateral triangular glass prism when a ray of light undergoes minimum deviation, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Angle of the Prism**:
Since the prism is equilateral, each angle of the prism is 60 degrees. Therefore, the angle of the prism (A) is:
\[
A = 60^\circ
