Wave-Particle Duality Double-Slit Experiment
The Double-Slit Experiment was first performed in 1801 by Thomas Young to provide support for a wave theory of light. Recreate one of the most important experiments in the history of physics and analyze the wave-particle duality of light with this easy classroom demonstration designed for high school level physics students.
