Question

Explain the refraction of light through a glass slab with a neat ray diagram.​

Answer 1

Hey, Mate,

Refraction of light through a Glass Slab.

Answer 2

Answer:

A ray of light EF in air is incident on the glass surface PQ at point O. ... As the ray EO enters from air (rarer medium) to glass (denser medium), the ray bends towards normal and follows the path OOl inside the glass slab.

Explanation:

AE = incident ray;

I = Angle if incidence;

R = Angle of refraction;

• On entering the glass slab the light ray bends towards the normal and travels along EF.

• The refracted ray EF is incident on the face SR at angle of incidence r’.

• The emergent ray FD bends away from normal at angle of refraction e.

• The emergent ray FD is parallel to the incident ray AE but it has been laterally displaced with respect to incident ray.
