How It Is Used
As the anode voltage is changed, the ring radii change. Measuring them and using the lattice plane spacing of graphite gives the electron wavelength as a function of anode voltage, which students compare with de Broglie's relation.
Frequently Asked Questions
What does the Teltron Electron Diffraction Tube S demonstrate?
