In the figure, a light wave along ray r reflects once from a mirror and a light wave along ray r2 reflects twice from that same mirror and once from atiny mirror at distance L from the bigger mirror. (Neglect the slight tilt of the rays.) The waves have wavelength 616 nm and are initially exactly out of phase. What are the (a) smallest, (b) second smallest, and (c) third smallest values of Lthat result in the final waves being exactly in phase? (a) Number 308 Units This answer has no units (b) Number 616 Units This answer has no units (c) Number 924 Units This answer has no units

In the figure, a light wave along ray r, reflects once from a mirror and a light wave along ray ro reflects twice from that same mirror and once from a tiny mirror at distance L from the bigger mirror.
