Question

Explain about lateral and vertical shift experiment
​

Answer 1

Answer:

Distance between emergent ray and divergent ray is known as vertical shift. When light rays travel across two parallel surfaces, the emergent rays from the second surface are parallel to the incident rays on the first surface. The perpendicular distance between them is called the lateral shift.

pls mark as brainliest.

Answer 2

$\large\tt\underline{\red{Answer :-}}$

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
