What is retraction through glass slab???

Answers

Answered by Anonymous

Refraction through a rectangular glass slab and principle of reversibility of light: On entering the glass slab, it bends towards normal and travels along EF at an angle of refraction r. ... The refracted ray EF is incident on face SR at an angle of incidence r' .

Answer:

When light Rays travelling through air enter glass slab, they get refracted and bend towards the normal. Now the direction of refracted ray changes again when it comes out of the glass slab into air... In this case incident ray and the emergent ray are parallel to each other...
