Possible Photon Energies

SATPHY-DFYMXQ

The diagram below represents the energy states for a particular kind of atom. Many of these atoms in the ground state are being exposed to electromagnetic radiation made up of photons with energies of $8\ eV$.

What are the possible energies of photons emitted by atoms "excited" by the initial electromagnetic radiation as the atoms return to the ground state?
