Several subscribers contacted us to show us the double slits and patterns they created following our video. Thank you all so much! If you have any questions, please contact us, and if you create a good double slit and a good pattern, please don't hesitate to show it to us. We're so excited when someone successfully completes an experiment following this video!

In this video, we'll see how we can create a double slit to reproduce the famous double-slit experiment, using photons produced with a laser.

Any laser pointer will work to reproduce the experiment. The most common ones have these wavelengths:
Red laser: 600 to 650 nm
Green laser: 523 nm
Violet/blue laser: 405 nm
