Principle of Reversibility of Light – Explained Principle of Reversibility of Light Question: The principle of reversibility states that light will follow exactly the same path if its direction of travel is reversed. This works for reflection. For example, in (a) going left to right, the angle of incidence equals the angle of reflection. If…
