The principle that if a beam of light is reflected back on itself, it will traverse the same path or paths as it did before reversal.
The principle of reversibility states that light will follow exactly the same path if its direction of travel is reversed.
Hence:
Using Snell's Law,
sin i | = 1n2 | sin r | = 2n1 |
1n2= | 1 2n1 |
It follows that
1n2= | 1 2n1 |

When a light ray travelling from one medium to another and allowed it to strike a plane mirror placed perpendicular to it then it was found that the light ray retraces its path.This is called reversibility of light.
For better sake of convinence I will send diagram of it.Thanks friends

Light is a collection of wavelengths that are fitted to a scale called the electromagnetic spectrum.? I shall use visible light to talk about here, which is found in the center of the electromagnetic spectrum.? The visible light colors are red, orange, yellow, green, blue, indigo, and violet.? All these colors have specific wavelengths and frequencies.? When you speak of reversibility of light, it has the capability of reflecting off an object.? Sometimes, the light will travel back the same exact path it took to get to the object it reflected off of in the first place.? The light wave simply reverses itself.? You can demonstrate this by holding a flashlight in front of a plane mirror, shining it straight into the mirror and seeing the light being reflected back to the flashlight itself.? Be sure to use a plane mirror (one that is flat) and not a concave or a convex mirror.

Hi,
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.
Hope this helps !
