Question

Incorrect stion 8 0/2 pts Electronic Transitions are often described in terms of ninitial (where the electron starts out) and nrinal (where the electron moves to). Which of these transitions involves the absorption of the most energetic photon? ninitia and final=4 ninitial -1 and nnnals ninitial4 and nfinal1 ninitial-2 and final=1

Answer 1

Energy gap would be maximum in case where number of states is maximum in between initial and final state if the states are separated by same energy gap.

So it is clear that transition should be between two n (1,4).

But the question asks about energy absorbed. And energy is only absorbed when an electron goes from lower energy level to higher energy level.  

On other hand if electron goes from higher level to lower level, energy is released.

Thus in this case initial state is n=1 and final state n=4
