Question

I couldn't understand please make me understand that a lateral displacement is directly proportional to the thickness of glass slab refractive index and as well as angle of incidence​

Answer 1

Answer:

Lateral displacement is directly proportional to the thickness of glass slab , the more is the thickness of glass slab more is a lateral displacement. hence, If the glass is more thick its density will be more.

In geometric optics, the angle of incidence is the angle between a ray incident on a surface and the line perpendicular to the surface at the point of incidence, called the normal. ... In the figure below, the line representing a ray makes an angle θ with the normal (dotted line).
