Say for a simple hydrogen atom, an electron absorbs just the right amount of energy such that it jumps up from energy levels n = 1 to n = 5. When it comes back down, is it possible to say, do n = 5 to n =3 to n = 2 to n =1, releasing 3 photons with their respective specific frequencies/energies? Or is it only able to go from n = 5 to n = 1? And why? Thanks in advance. It's not a homework question, it's a question that came out of a classroom discussion.
