Textbook Question
Chapter 6, Problem 60GQ
Suppose hydrogen atoms absorb energy so that electrons are excited to the n = 7 energy level. Electrons then undergo these transitions, among others: (a) n = 7 → n = 1; (b) n = 7 → n = 6; and (c) n = 2 → n = 1. Which of these transitions produces a photon with (i) the smallest energy, (ii) the highest frequency, and (iii) the shortest wavelength?
