Question

what do we call the distance 'd' between the parallel lines in glass slab experiment​

Answer 1

Answer:

Lateral displacement is the answer

Answer 2

The distance 'd' between the parallel lines in glass slab experiment is known as - 'lateral displacement'.

Lateral displacement is perpendicular distance between incident and emergent ray when light ray get through refraction from glass slab.

Factors on which lateral displacement depends: are-

• The thickness of the glass slab

• Refractive index of the glass slab

• The angle at which incident ray enters the glass slab
