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?
