The tube can be used for demonstration of the electron's wave nature, as well as an opportunity to measure the Broglie wavelength of the electron. Along with photoelectric power, electron diffraction illuminates one of the most revolutionary results of quantum mechanics: the duality between particles and waves.
The wave nature of the electron is detected in the tube by passing the electron beam on a polycrystalline graphite film which deflects the wave packets.
From a knowledge of the lattice constants in graphite, the Broglie wavelength of the electrons can be determined, as well as its variation in the energy studied.
The tube is used in the holder 508060 (optional).
Anode voltage up to 5 kV.
Glow voltage max. 7.5 V.
