American Institute of Physics: Discovery of the Electron
Use this resource to read about the "Experiments by J.J. Thomson in 1897 [which] led to the discovery of a fundamental building block of matter." This exhibit is organized into several sections, including: "Mysterious Rays" and "1897...
University of Colorado
University of Colorado: Ph Et Interactive Simulations: Davisson Germer
Simulate the original experiment that proved that electrons can behave as waves. Watch electrons diffract off a crystal of atoms, interfering with themselves to create peaks and troughs of probability. Java required.
