In the Cathode Ray Experiment used to discover the electron,
(This is what my textbook says (Grade 11) so if there's any additional parameters that I do not know of I apologize)
The cathode ray tube has two electrodes and a evacuation. Under low pressures when high voltage is passed through the Electrodes, a stream of particles can be seen. Its presence was further confirmed by perforating the anode and by adding a phosphorescent coating of Zinc Sulphide behind it.
My question is since the anode is perforated will we see deflection of electrons towards the edges of the perforations because the eletrons tend to flow towards the anode so i see no reason for it to pass through the holes instead of deflecting towards the perforation boundaries.
