WebAccording to wave-based theories, the light waves spread out from the source in all directions, and upon striking a mirror, are reflected at an angle determined by the angle at which the light arrives. The reflection process inverts each wave back-to-front, which is why a reverse image is observed. WebExpert Answer. arrow B is the reflected ray …. Light ray A moves from air to water.
