Calculate the shift produced by the slab having thickness 15cm and refractive index 1.5 which is kept in air.

Explanation

To calculate the lateral shift produced by a glass slab with a thickness of 15 cm and a refractive index of 1.5, we can use the formula for lateral shift (s) given by:

\[ s = t \left(1 - \frac{1}{\mu}\right) \]

where:
- \( s \) is the lateral shift,
- \( t \) is the thickness of the slab,
- \( \mu \) is the refractive index of the slab.
