555626 Electron Diffraction Tube
Overview
To demonstrate the wave nature of electrons by diffraction on a polycrystalline graphite grid (Debye-Scherrer interference), observation of the interference rings on the light screen, confirmation of the de Broglie equation by determining the wavelength at different anode voltages, includes magnet for alignment, fastening on the tube stand (555 600).
