Hi to all, I have a quantum question to post here. In the discussion on atomic theory, we know that electrons in different orbital levels have different quantum energy, say n=1 and n=2 have different energy levels. When one electron 'jumps' to another energy level, say from n=2 to n=1, the demotion will release a photon with energy equal to the energy level difference. On a macroscopic level, if I take a lift from level 2 to level 1, do I release a photon of similar energy as well? Consider that a macroscopic body is also argued to be made up of billions of microscopic bodies. Similarly, if I take a lift from level 1 to level 2, do I absorb a photon which will increase my energy level relative to a fixed point, say the Earth's surface? Pleae advise. Thanks.
