Draw a ray diagram to illustrate how a ray of light incident obliquely on one face of a rectangular glass slab of uniform thickness emerges.

Explanation

To draw a ray diagram illustrating how a ray of light incident obliquely on one face of a rectangular glass slab of uniform thickness emerges, follow these steps:

### Step-by-Step Solution:

1. **Draw the Glass Slab**: Start by drawing a rectangular shape to represent the glass slab. Label the top side as the "Air" medium and the bottom side as the "Air" medium as well.

2. **Identify the Incident Ray**: Draw a straight line approaching the glass slab at an angle. This line represents the incident ray. Label this ray as "Incident Ray".
