Which of the following transitions (in a hydrogen atom)represent absorption of the smallest frequency photon?
A) n = 5 to n = 6
B) n = 5 to n = 1
C) n = 4 to n = 1
D) n = 1 to n = 5
E) n = 2 to n = 5

Question

Quizplus · Accepted Answer

The frequency of a photon absorbed or emitted during a transition between energy levels in a hydrogen atom is determined by the difference in energy levels. The smallest frequency photon corresponds to the smallest energy difference, which occurs in transitions between adjacent energy levels. Among the options, the transition from n = 5 to n = 6 represents the smallest energy difference, and thus the absorption of the smallest frequency photon.
