step by step PLEASE HELP
A bottle contains a gas with atoms whose lowest four energy levels are -12 eV, -9 eV, -8 eV, and -2 eV. Electrons run through the bottle and excite the atoms so that at all times there are large numbers of atoms in each of these four energy levels, but there are no atoms in higher energy levels. List the energies of the photons that will be emitted by the gas. Give the lowest photon energy first and the highest photon energy last: Next the electron beam is turned off, and all the atoms are in the ground state. Light containing a continuous spectrum of photon energies from 0.5 eV to 15 eV shines through the bottle. A photon detector on the other side of the bottle shows that some photon energies are depleted in the spectrum ("dark lines"). What are the energies of the missing photons? Give the lowest missing photon energy first and the highest missing photon energy last:Explanation / Answer
The dark lines will correspond to absorbed photons,and the three possible absorbtion energies are
3 ev ,4 ev and 10 ev.
