Question

what is lateral shift?explain with the help of a labelled diagram?

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.

See diagram in the practical book.

Hope it help u most.

Answer 2

$\underline \bold {Answer}$

When a denser medium is kept between two parallel faces inside a rare medium and a ray falls upon one of the two parallel faces reflects into the denser medium and comes out of another surface becoming parallel to the incident ray.

In the successive reflection the deviation at first surface is reversed at second surface but the emergent ray deviates literally.

The distance to what an emergent Ray devited from the direction of incident ray when suffers refraction at two parallel surfaces is called as lateral deviation/ displacement.

The lateral displacement/deviation increase with the increase in

• thickness

• angle of incident

• optical density
