Answer: The law of refraction can be defined as:
Case 1:- incident ray>refracted ray
the bending of the refracted ray towards the normal which is drawn at the point of incidence when the ray light is passing from air to glass i, e; the light is passing from the rare medium to the denser medium.
Case 2: -incident ray< refracted ray
the bending of the refracted ray away from the normal which is drawn at the point of incidence when the ray light is passing from glass to air i, e; the light is passing from the denser medium to the rarer medium.
