Problem
A rectangular glass slab of thickness 4.0cm and refractive index 1.5 is placed in air. A ray of light is incident on the upper surface at an angle of 30∘ to the normal. Answer the following:
(i) Find the angle of refraction inside the glass slab.
(ii) Calculate the lateral displacement between the emergent ray and the original direction of the incident ray.
