Question

define absolute refractive index and lateral displacement​

Answer 1

$\huge\boxed{\fcolorbox{black}{pink}{Answer}}$

Absolute refractive index of a medium is defined as the ratio of the velocity of light in a vacuum to the velocity of light in the medium. If c is the velocity of light in vacuum and v in the medium, then: n=c/v. The value of the absolute refractive index can never be less than 1.

Lateral Displacement is the perpendicular distance between the emergent ray from a glass slab and the incident ray produced forward.

The absolute refractive index is defined as the ratio of the speed of light in vacuum and in the given medium. The absolute refractive index should never be less than 1.

When the perpendicular distance between the original path traced by an incident ray and the path traced by the emergent ray coming out from the glass slab is known as lateral displacement.
