The Two-Slit Experiment
We will first examine an experiment which Richard Feynman says contains “all of the mystery of quantum mechanics”.
The general layout of the experiment consists of a source, two-slits, and a detector as shown below;
The idea is to investigate three different sources (a classical particle (bullets), a classical wave (water), and a quantum object (electron or photon)). We will study the spatial distribution (x) of the objects which arrive at the detector after passing through the slits.
