Double-slit experiment revisited....again....

A forum set up for physics questions from students in the courses PHYS1121, 1131, 1221 and 1331 at the University of New South Wales. It is intended for questions that cannot readily be answered in class,
either because they fall outside the main syllabus and therefore would be distraction (however interesting) or for other reasons.

I had the same problem but it worked after right click and "Save Link Target As...."


The electrons have a well defined momentum and so take a very similar time to pass through the apparatus. However, their arrival time at the apparatus is probabilistic.

In the beginning, when there are only few arrivals recorded, they probably show the film at a slow rate, and at the end, when dealing with lots of electrons, they probably show it at a fast rate.

Joe
The first 40 sec segment I believe is playing at a slow rate but same rate, at this segment it seems that there are electrons appearing inconsistantly with linear time increment.

We've now put a video of an experimental demonstration of Young's experiment with single photons. It's at

The introduction to Young's experiment itself and to the nature of light are at
