Davisson-Germer: Electron Diffraction
|
About
Topics
- Electron Diffraction
Description
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.
Sample Learning Goals
- Recognize that electrons are reflected from a lattice mostly at certain angles due to wave interference.
