The Compton's Apparatus is not good enough of an explanation. I would like to know at a fundamental level the geometry of both the entire atom and photon and what causes a photon to give off only some energy as kinetic.
It would help to know what happens at that level because creating light propulsion would be ideal for all forms of travel. Better materials could be created in maximizing energy conversion to kinetic energy rather than having most energy lost as heat or in reflection.
While true, that doesn't have anything to do with whether a photon or electron has dimensions.A beam of light requires space. No space would mean no reference to anything not even to itself.
That is a meaningless combination of concepts.Electron configurations are shown for atoms, so why isn't there a photon configuration as well?
I think you're missing a critical concept here: the energy of the photon does not and cannot change. And the value of the momentum doesn't change either, only the sign. This is easy enough to see using the equations for the two concepts:So a photon in a chamber of perfectly reflective surfaces would lose all of its energy eventually by momentum transfer solely? Still, why cant the photon lose all its energy as kinetic?
