Electron Diffraction
video embedded
Type of activity: demo
Activity code: Mo-001
Description:
| Demonstrates the wave nature of the electron. See faraday.physics.utoronto.ca/IYearLab/elecdiff.pdf |
Principle:
|
Fast electrons are diffracted from a polycrystalline layer of graphite: interference rings appear on a fluorescent screen. The interplanar spacing in graphite is determined from the diameter of the rings and the accelerating voltage. |
