Experiment : Double Slit
I tried to reproduce the Double-Slit experiment with a cheap red laser-diode (<1mW).
Below are various results obtained from some variations of the experiment ... (with a double slit, with a pinhole, with a thin wire, and with a hair (and also with a single slit who gave almost the same result than with a hair))
I also tried to reproduce it with an other source of light (and got electrocuted). But so far, I'm not satisfied by the results I obtained with the light bulb, and I failed with the sun.
Do you have some experience to share about this experiment ?
Do you have successfully reproduced it with an other source of light than a cheap laser diode ?
