Lateral displacement of ray passing through a glass slab
A ray of light is incident on a parallel sided glass slab of refractive index n and thickness t as shown in Fig. 34-2. Find the lateral displacement of the ray as it passes through the slab.

Explanation

To find the lateral displacement of a ray passing through a parallel-sided glass slab, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Setup**:
- We have a glass slab with thickness \( t \) and refractive index \( n \).
- A ray of light is incident on one face of the slab at an angle of incidence \( i \) and refracts into the slab at an angle \( r \).
