Question

Name the term given for the gap between the emergent ray and extended incident ray during refraction of light from a glass slab

Note: Wrong answers will be *Reported*​

Answer 1

Answer:

Lateral displacement is the name of the such gap

Answer 2

The term for distance between emergent ray and extended incident ray during refraction of light from a glass slab is called Lateral Displacement.

• When light is allowed to fall on a glass slab, it undergoes refraction on its surface through an angle called angle of refraction(∠r).
• Then the ray undergoes another refraction on the parallel surface of the glass slab through another angle .
• Upon extending the incident ray and the ray that emerges from the glass slab, we find that both rays are parallel to each other.
• The perpendicular distance between the extended incident ray and emergent ray is called Lateral Displacement.

Thus, correct answer is Lateral Displacement .
