Light has no mass. It has a momentum, though. That means it can potentially push things when reflected and therefore lose energy due to the doppler effect, right? Does it mean that it gains energy when it slows down things and doesn't lose any energy if it doesn't push anything? If the whole thing has nothing to do with the doppler effect, then please tell me how it works.
Thanks
