As we increase the accelerating voltage, electrons are gaining more and more kinematic kinetic  energy and they are colliding with atoms elastically until the kinematic kinetic  energy reaches the first excitation level of the atom. When the first excitation level is reached, inelastic collisions occur and the electron will transfer all the kinematic kinetic  energy it has to the atom (refer to Fig. \ref{fig:collisions}). This corresponds to a dip in current detected by the anode due to the sudden decrease of electrons that reach the anode. As the accelerating voltage keeps increasing, there will be continues to increase  more dips, dips will occur,  corresponding to multiple integers of inelastic collisions happened in the tube. These dips in current explained the quantum nature of atoms.
