Hi,
I am a newby so please excuse my ignorance.
With reference to the single electron double slit experiment, one thing has been bugging me. The videos that illustrate the particle or wave behaviour do not tell us how the single fired electrons are directed to either the left or right slit. If the electron gun is directed to the right slit and doesn't move surely the electrons will always go through the right slit and the same would apply if the gun was pointed at the left slit, they would always travel through the left slit. I imagine the path of the electron to be straight and fixed. i.e. (while observed) each repetitive firing would result in a single bar on the backplate behind either the left or right (wherever the gun was pointed). This would be the result if you set up a rifle to fire bullets through only one slit each time.
Is the electron gun oscillating between the two after each single fire? the marble analogy shows us that the marbles are coming out randomly across the path of both slits, so therefore some hit the plate, some travel through the right and some through the left slits, hence the double bar pattern.
What give the electron paths a similar random direct path from gun to plate/right/left slit...surely the gun must be moving in some way across the arc of the two slits.
Also, has there ever been an experiment to fire two single electrons simultaneously from two separate guns, one to the left slit and one to right slit. If so what were the unobserved / observed results from that?
Many thanks
Tom
