Question

what is lateral displacement of a light ray passing through a glass slab

Answer 1

hey here is your answer

Refraction through a glass slab. So,the incident ray is parallel to theemergent ray but it is laterallydisplaced from it. Question: A ray oflight travelling in air falls on thesurface of a transparent glass slab.The ray makes and angle of 45∘ withthe normal to the surface.

hope you understand

Answer 2

$Here \: is \: the \: answer \: of \: your \: question$


As we know that light travels in a straight line... The glass slab is denser and air is denser. Then light ray moves towards the normal and the next time the light ray move from denser to rarer so it moves away from the normal. Due to this variations, the light ray is laterally displaced.


The incident ray or light and emergent ray or light are parallel to each other. Because after making angle with normal the light don't travel in straight line. Instead of travelling straight it deviate from it's path and bend...


Emergent ray or light and incident ray or light are the factors which determines the lateral displacement of a ray of light passing through a rectangular glass slab...
