The double-slit experiment is a famous tool to illustrate concepts within quantum mechanics. In particular it demonstrates the concept of wave-particle duality. Use of a light wave demonstrates diffraction and interference, which is a typical wave behaviour. Surprisingly, use of a beam of electrons also yields an interference pattern, showing electrons can behave like waves.
The two-slit diffraction experiment shows how light can be treated as particles and how light waves carry the statistical information for the experiment. if we were to use a beam of electrons instead of light in the experiment, how would the results differ?
