Question

What is understood as lateral displacement of light? Illustrate this with the help of a
diagram. List two factors on which the lateral displacement in a particular substance
depends.

Answer 1

A ray of light travels in a certain straight line path. After refraction through a glass slab, it emerges in a direction parallel to the original direction but slightly displaced from the line. This is called the lateral displacement.

Answer 2

Answer:

Lateral Shift or Lateral Displacement

• It is the shift or displacement of the emergent ray.
• It is also the perpendicular distance between the incident ray and the emergent ray.

Lateral Shift or Lateral displacement depends upon the following things:-

• Thickness of the glass.
• Refractive index.
• Angle of incidence.
• Wavelength of the incident light.
