A thick rectangular glass slab is kept inside a water trough. A ray of light passing through water is incident on the glass slab at an angle of `45^(@)`. Calculate the angle of refraction, if refractive indices of water and glass are 1.33 and 1.45 respectively.

Explanation

To solve the problem, we will use Snell's Law, which relates the angles of incidence and refraction to the refractive indices of the two media involved.

### Step-by-Step Solution:

1. **Identify the Given Values:**
- Refractive index of water, \( n_1 = 1.33 \)
- Refractive index of glass, \( n_2 = 1.45 \)
- Angle of incidence, \( i = 45^\circ \)
