Question

Using the principle of reversibility, prove that
medium 1​

Answer 1

Principle of reversibility of light - law

This means that if a light ray travels from medium 1 to medium 2 and has angle of incidence and angle of refraction as i and r respectively, then if the light is incident from medium 2 at an angle r, then the angle of refraction in medium 1 will be i.

Answer 2

Answer:

PRINCIPLE OF REVERSIBILITY OF LIGHT - LAW

concept

According to principle of reversibility of light, if the path of the light is reversed after suffering a number of reflections and refractions, then it retraces its path. This means that if a light ray travels from medium 1 to medium 2 and has angle of incidence and angle of refraction as i and r respectively, then if the light is incident from medium 2 at an angle r, then the angle of refraction in medium 1 will be i.
