Question

A ray of light is incident at a small angle @ on a rectangular glass slab
of thickness t. If the refreactive index of glass is u, show that the
perpendicular distance between the emergent ray from the slab and the
incident ray is toqu - 1)/u.
​

Answer 1

Answer:

The ray of light which falls on the mirror surface is called the incident ray. The angle .If the angle between the incident and reflected rays ... The mirror formula is relation relating the object distance (u), the image distance (v) and the focal length (iii) Lateral shift is directly proportional to the refractive index of glass slab.
