Question

With the help of a proper diagram, explain how is light refracted through a glass slab? Define lateral displacement. Give any two factors on which the lateral displacement depends.

Answer 1

Answer:

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. At point Ol, refraction enters from glass (denser medium) to air (rarer medium) the ray bends away from normal and follows the path OlH outside the glass slab.
