Question

definition of lateral displacemen

Answer 1

Lateral displacement

It is the distance between the emergent ray and the incident ray to the surface being produced forward

Refer to the attachment:

Here, XY is the lateral displacement

What is incident ray?

An incident ray is a ray of light that strikes a surface. The angle between this ray and the perpendicular or normal to the surface is the angle of incidence.

Here, AO is the incident ray which is produced to D in the same direction

What is emergent ray?

Emergent ray is the ray which emerges at the source of light. incident ray is an acronym of emergent ray. it is a light which leaves a medium.

Here, BC is an emergent ray

What is refracted ray?

A refracted ray is a ray that passes through an interface between two media and travels into the medium on the other side of the interface.

Here, OB is the retracted ray

Answer 2

Answer:

Lateral displacement. The perpendicular distance between the incident ray and the emergent ray is defined as lateral shift. This shift depends upon the angle of incidence,the angle of refraction and the thickness of the medium."
