A parallel beam of light is incident on a rectangle transparent plate of thickness 8 cm. The angle of incidence and refraction of the beam is `60^@ and 30^@` respectively. Find the lateral shift.

Explanation

To find the lateral shift of a parallel beam of light incident on a rectangular transparent plate, we can follow these steps:

### Step 1: Identify the given values
- Thickness of the plate (t) = 8 cm
- Angle of incidence (i) = 60°
- Angle of refraction (r) = 30°

### Step 2: Use the formula for lateral shift
