Hydrogen atoms absorb energy so that electrons can be excited to the n = 6 energy level. Electrons then undergo these transitions, among others: (a) n = 4 ā n = 3 (b) n = 6 ā n = 3 (c) n = 5 ā n = 4 (i) Which transition produces a photon with the least energy? (ii) Which transition produces a photon with the highest frequency? (iii) Which transition produces a photon with the shortest wavelength?
