The principle of reversibility states that light follows the same path if the direction of light is reversed. The refractive index of light when it passes from the first medium to the second medium is the same as the refractive index of light when it goes from second medium to the first medium.

Answer 2

$\huge{ Answer }{\heartsuit}$

The principle of reversibility of light states that light follows the same path if the direction of the travel of light is reversed. In its simplest explanation, the principle of reversibility is a deduction of Snell's law of the refraction of light.
