Problem
Two allowed energy levels in an atom differ by an energy ΔE. If that difference is reduced to 21ΔE, briefly describe how the wavelength of the photon emitted in a transition between the new pair of levels compares with that of the original transition. Explain your reasoning in one or two sentences.
