What Is The Principle Of Reversibility?

Answer:

The principle of reversibility of light states that light follows the same path if the direction of the travel of light is reversed.

The principle of reversibility presumes that the attenuation of a light ray during its passage through an optical medium because of reflection, refraction, and absorption is not affected by a reversal of the direction of the ray. In its simplest explanation, the principle of reversibility is a deduction of Snell’s law of the refraction of light. The principle of reversibility presumes that the attenuation of a light ray during its entrance through an optical medium due to reflection, refraction, and absorption is not changed by a reversal of the direction of the ray.

Principle of Reversibility of light

If the direction of a ray of light is reversed due to reflection off a surface, then it will retrace its path.
