I know that an atom has energy levels i.e the energy of each electron in the atom falls in a discrete energy level.
I am also aware that, if the exact difference of energy between two levels is provided to an electron, then it jumps to the higher energy level, and that is a lower amount of energy is provided, the electron stays where it is.
My questions are:
- What happens to the energy in the second case? Does it get radiated back as heat? If not, where does that energy go?
- What happens if more than the requisite amount of energy is provided? Does the electron stay where it is, or does it go to the higher energy level?
