Relying on this fact that not only role of the medium (intermediate gas) cannot be ignored in the electric discharge between cathode and anode, but also it is very important, the diffraction and interference phenomena which an electron beam can reveal are justified. This act is done after analyzing the manner in which stroke propagates via the gas valence electrons. In this respect an experiment is proposed as a test. We conclude that the cathodic ray does not carry charge, ie is not a ray of electrons being shot but is a longitudinal wave arising from the vibration of the valence electrons of the molecules of the wave-carrying medium. In this way the mechanism of production of and the difference between the longitudinal and transverse waves and that our longitudinal wave is only due to compression (not expansion) impacts are explained.
Our ability for complete deflecting and making away the electron beam (behind the anode), existence of sharp shadow of anode in the electric discharge tube, existence of dark-bright striated columns in this tube (similar to Kundt tube in acoustics), and the action mechanism of image intensifying in the image intensifier tubes are all described as witnesses to confirm the wave-like motion for electron beam proposed in this paper and reject the shooting motion for it.
Deflection of the trajectory of electron beams in electric and magnetic fields is justified in wave-like motion of "going" and "backing" for evaluation of which an experiment has been proposed. It is shown that how for transferring of momentum there is no necessity to suppose shooting motion for electron in the cathodic ray.
Two separate parallel cathodic rays repel each other. This will be contrary to what the electromagnetism predicts if a cathodic ray is to carry charge. This phenomenon is justified by the model presented here.
