An equilateral glass prism `(mu - 1.6)` is immersed in water `(mu = 1.33)`. Calculate the angle of deviation produced for a ray of light incident at `40^@` on one face of the prism.

Explanation

To solve the problem step by step, we will follow the procedure outlined in the video transcript while breaking it down into clear steps.

### Step 1: Calculate the Refractive Index of Glass with Respect to Water
The refractive index of the glass prism with respect to water (μg/w) can be calculated using the formula:
\[ \mu_{g/w} = \frac{\mu_{g}}{\mu_{w}} = \frac{1.6}{1.33} \]
Calculating this gives:
