A ray of light travels from water to glass. The angle of incidence is `40^(@).` Calculate the angle of refraction and the deviation produced.
Given: `n _(g) = 1. 5 and n _(w) = 1.3`

Explanation

To solve the problem of a ray of light traveling from water to glass, we will use Snell's Law, which relates the angles of incidence and refraction to the refractive indices of the two media.

### Step-by-Step Solution:

1. **Identify Given Values**:
- Angle of incidence (I) = 40°
- Refractive index of water (n_w) = 1.3
- Refractive index of glass (n_g) = 1.5
