A parallel sides glass slab of thickness 4 cm is made of a material of refractive index `sqrt3`. When light is incident on one of the parallelfaces at an angle of `60^(@)` , it emerges from the other parallel face. Find the lateral displacement of the emergent beam.

Explanation

To find the lateral displacement of the emergent beam when light passes through a parallel-sided glass slab, we can follow these steps:

### Step 1: Understand the Problem
We have a glass slab of thickness \( t = 4 \, \text{cm} \) and a refractive index \( \mu = \sqrt{3} \). Light is incident on one of the parallel faces at an angle of \( 60^\circ \). We need to find the lateral displacement of the emergent beam.

### Step 2: Use Snell's Law
According to Snell's Law:
\[
