Davisson-Germer: Electron Diffraction

Davisson-Germer: Electron Diffraction Screenshot Download 2,082 kB
Version: 1.11 (change log)
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.

Teaching Resources

Main Topics

  • Electron Diffraction

Sample Learning Goals

  • Recognize that electrons are reflected from a lattice mostly at certain angles due to wave interference.

Tips for Teachers

The teacher's guide (pdf) contains tips created by the PhET team.
