Question

What is the lateral displacement when light falls normally on glass slab??(90 degree)

Answer 1

Answer:

HEY MATE!!

When a ray of light is incident obliquely on a parallel. sided glass slab the emergent ray shifts laterally . The perpendicular distance between the direction. of the incident ray and emergent ray is called. “lateral shift''.

Answer 2

Answer:

When light falls perpendicularly or normally on the surface of a glass slab, it goes straight. There is no bending of ray of light on entering the glass slab or coming out of it. In this case angle of incidence and angle of refraction is zero.
