Question

the ratio of a lateral displacement of a any layer to its distance form the fixed layer is called​

Answer 1

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

Answer 2

The ratio of the lateral displacement of a layer to its distance from the fixed layer is known as the refractive index of the medium.

Explanation:

• When the refractive index of the medium is different then there is bending of light when light comes from one of the layer to the other layer.

• And when it exits that medium there is bending and a perpendicular distance which is left. This depends on the refractive index and the thickness of the glass slab. The refractive index is nothing but the ratio of the lateral displacement and the thickness of the layer.
