What accelerating voltage would find first dip in current

Reference no: EM131000741

The transition from first excited state to the ground state of K (potassium) results in emission of a photon lambda = 770 nm (deep red-color) if the K vapors are used in Franck-Hertz experiment. At what accelerating voltage you would find the first dip (decrease) in current?
