5. Assume that a hypothetical object has just four quantum states with the followingenergies:-1.0 eV (third excited state)-1.8 eV (second excited state)-2.9 eV (first excited state)-4.8 eV (ground state)a. Suppose that a material containing many such objects is hit with a beam ofenergetic electrons, which ensures that there are always some objects in allof these states. What are the six energies of photons that could be stronglyemitted by the material? (In actual quantum objects there are often"selection rules" that forbid certain emissions even though there is enoughenergy; assume that there are no such restrictions here.) List the photonemission energies.b. Next, suppose that the beam of electrons is shut off so that all of the objectsare in the ground state almost all the time. If electromagnetic radiation witha wide range of energies is passed through the material, what will be thethree energies of photons corresponding to missing ("dark") lines in thespectrum? Remember that there is hardly any absorption from excitedstates because emission from an excited state happens very quickly sothere is never a significant number of objects in an excited state. Assumethat the detector is sensitive to a wide range of photon energies, not justenergies in the visible region. List the dark-line energies.
