I'm a sophomore majoring in physics, and I had some question about the discrete energy value of atoms and its excitation.
So, I know that in order to make a hydrogen atom in a ground state to get "excited" to its 1st excited state we need 10.2eV. For 2nd excited state, we need 12.1eV.
My question is this: Will a photon with the energy value 11eV excite the hydrogen atom? Or will it just provide no energy to the atom and go away?
Also, if I "shoot" a photon with the energy 12.1eV to the atom, will it get excited to its 2nd excited state? Or is there any possibility the atom will be excited to its 1st excited state?
If the atom can be excited to either the 1st or the 2nd excited state, are the possibilities the same?
