Double Slit Light Experiment

cults3d

Light behaves like both waves and particles, depending on how it's observed. The double slit experiment using coherent light reveals this duality. By setting up a simple apparatus with a laser pointer and a single or double slit gate made of paper or aluminum foil, you can conduct your own experiment at home. What will happen is worth predicting, but all you need are some printed parts, a laser pointer, and some paper and/or aluminum foil. The printed parts include a stand for the laser pointer, a frame to hold the gate material, an alligator clip to secure it in place, and a circular clip to keep the laser button pressed down. Printing multiple sets of frames and alligator clips allows you to quickly switch between different gates and observe the results of your experiment.
