Let's say there are three states ofor energym, E1, E2 and E3, and the electron is at E1, what happens if a photon has energy E > E2-E1 ?
Does it interact to the electron anD take it to E2 and the photon loose energy E2-E1 or it doesn't interact at ALL?
I mean, the electron can't have an energy greater than E2 and be in state E2

An electromagnetic wave can cause transitions between energy states of an atom even when it's not at exact resonance with the transition energy, but it will just as quickly cause a stimulated emission that brings the atom back to the original state. This can be shown by adding an oscillating time-dependent term in the Hamiltonian matrix of a 2-state system and solving the occupancies of the two energy states as a function of time.

in general the Frank-Hertz experiment showed the discrete nature of atomic transitions. the target atoms were invisible to electrons except for the energies shown below ie for cases like;

"

Does it interact to the electron anD take it to E2 and the photon loose energy E2-E1 or it doesn't interact at ALL?"


the fact the line widths are not infinitely narrow is prolly worthy of a different thread.
