Thomas Young's Double Slit Experiment
Why Physics Stack Exchange recommends it
Physics Stack Exchange users link it as a clear visual of the real laser, double slit and screen setup and the interference pattern it produces.

What it is
A short MIT K-12 educational video that demonstrates Thomas Young's double slit experiment with a laser, a double slit and a screen. It shows how light waves interfere to produce a pattern of bright and dark fringes.

Here is a video [this video] which shows the experimental setup of laser, double slit and screen and no single slit producing the interference pattern.

This may help [this video] for light. The difference with a double slit with electrons set up here [LINK] and the wave nature here [LINK] . It aint simple, it needs mathematics.

Note that your first video is showing a simulation of the experiment [this video] . From the transcript: We don't have the equipment to do it for you, but we can show you a simulation of what you would see. Right now, you are watching an animation showing what we would expect to see if we could do the double slit experiment with only a small number of photons in a system at a time. Also note that "detectors prevent interference" is a prediction of quantum mechanics. It's not exclusive to collapse interpretations. With those noted... A paper that does an actual experiment and records the results is 'Controlled double-slit electron diffraction' by Roger Bach et al from 2013 [LINK] . They use a bloc

This video [this video] shows the change of a photon's interference pattern in real time of the Young's single and double slit experiment. In this video [LINK] it is claimed that by adding a detector to view how the photon moves through the slits the wave collapses and the screen will not show the interference pattern. The photon now behaves as a point particle. Where can I see video evidence of an experiment showing this happening "real time"? That is, run the experiment like in the first video, showing the interference pattern, and then turning on the slit detectors, showing the interference pattern change instantly.
