I blast a ground state electron with a photon that's energy equals 1.5 the energy difference between that energy level and the next. This is what happens to the electron.
What is
-The electron only absorbs enough energy to move up to the next energy level
-The extra energy is reflected
-Eventually, the electron falls back to ground state, emitting a photon with energy = to the difference between the energy levels
