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.
