010(part2of3)10.0pointsAn electron de-excites from the fourth quan-tum level to the third and then directly to theground state. Two photons are emitted.How does the sum of their frequencies com-pare to the frequency of the single photonthat would be emitted by de-excitation fromthe fourth level directly to the ground state?

2.The sum is smaller than the frequency ofthe single photon.3.The sum is larger than the frequency ofthe single photon.4.The sum is equal to the frequency of thesingle photon.011(part3of3)10.0pointsSuppose the four energy levels were somehowevenly spaced.How many spectral lines would result?
