Suppose a hypothetical object has just four quantum states, with the following energies:-0.8 eV (third excited state)-1.3 eV (second excited state)-2.6 eV (first excited state)-4.5 eV (ground state)(a) Suppose that material containing many such objects is hit with a beam of energetic electronsthat ensures that there are always some objects in all of these states. What are the six energies ofphotons that could be strongly emitted by the material?
