Question
**Problem 4-36:** The transition from the first excited state to the ground state in potassium results in the emission of a photon with a wavelength (λ) of 770 nm. If potassium vapor is used in a Franck-Hertz experiment, at what voltage would you expect to see the first decrease in current? *Note: This problem is related to quantum mechanics and experiments involving the excitation of electrons in atoms. The Franck-Hertz experiment is significant for demonstrating the quantized nature of energy levels in atoms.*
