All Chapters Video 2.9 Emission Spectra, Heisenberg Uncertainty, Photoelectric Effect (Solution) Chapter OutlineChapter Quiz Question? Ask Dr. Mike! Lesson Summary 1. Electronic transitions are accompanied by absorption or emission of light. Which electronic transition corresponds to emission of light with the shortest wavelength? A. n = 1 → n = 5 B. n = 3 → n = 1 C. n = 5 → n = 4 D. n = 2 → n = 3 E. n = 4 → n = 3 2. You have a photocell whose work function value equals 3 eV. If this photocell is struck with a photon that has an energy of 2 eV, will it produce a current? • In the previous question, if your photocell is struck by a photon with an energy of 5 eV, what will the resulting energy of the expelled electron be?
