Question

How does lateral shift depends on angle of incidence

Answer 1

Their is a small derivation which gives us the formula for lateral shift .it is

lateral shift = sec( r) x sin(i-r)

where r= angle of refraction
i= angle of incidence
so from here it is clear that lateral shift depends on angle of incidence.

Answer 2

It can be seen from its formula which depends on the value of I

$\underline \bold {Answer}$

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
