Question

what are the principle of reversibility of light

Answer 1

The principle of reversibility of light :-If the path of light is reversed after a number for reflections and refraction then it retraces it's path.Note the directions ofthe arrow.The beam of light travels back on the same path as it was traveling before the refraction and after the refraction after being encountered by the obstacle in the water.

Answer 2

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.
