Considering normal incident of ray, find equivalent refractive index of combination of two slabs shown in figure.

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.

A ray of light is incident on a glass slab at grazing incidence. The refractive index of the material of the slab is given by mu=sqrt((1+y) . If the thickness of the slab is d=2m , determing the equation of the trajectory of the ray inside the slab and the coordinates of the point where the ray exits from the slab. Take the origin to be at the point of entry of the ray.
