That makes some sense, so the photons should have a range of emitted energies between 4 eV and 7 eV right? Unfortunately, the only answer choice in my packet to this problem that includes 4 eV also has 9 eV, so I'm still missing something.
A gas of a hypothetical atom in ground state (-14eV) is irradiated with photons having a continuous range of energies between 7 and 10 electron-volts. Photons of which energies will be emitted from the gas?The energy levels look like this:
