This video was edited 30-12-2022. I removed everything but the experimental parts of the original video. The reason for this is that I was no longer behind the way I explained the experiments, especially the quantum aspects.

In the video I show you how you can use a microscope to visualize the EM- wave propagation after light has passed the slits.

WARNING: do not attempt to repeat this experiment without using a camera! Looking at laser beams under a microscope with your bare eyes instead of a camera can kill your eyesight instantly and leave you blind for the rest of you life.
