Hey,
It seems like this is impossible because momentum conservation is violated. I had a Q where an electron underwent an energy transition and emitted a photon, and then they asked whether it was possible for the photon to be reabsorbed by the electron to undergo the same transition as before (albeit in reverse this time, lower to higher energy level).
Could someone explain why momentum conservation is violated here? Also, the Q suggested that in theory, a centrifuge could 'address' this problem. How exactly?
Thanks!
