Question

what is the formula for principle of reversibility of light​

Answer 1

Answer:

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.

Answer 2

Explanation:

The path of light can undergo many changes as light goes from its source to your eye. To analyze the path it is useful to know that the path is reversible. If you trace the path from water to air to glass, you can reverse the direction and follow the same path from glass to air to water
