Hi All, I'm pondering some questions around photon absorption causing bound electrons to move to higher energy levels. When a photon strikes an atom, what will happen if the photon has more than enough energy to make an electron move to the first excited state, but not enough for it to move to the second. Surely it will still be absorbed? But what happens to the extra energy? Would it be re-emitted? Wouldn't this result in a broader range of frequencies being emitted than we actually see? Many thanks for your help.
