Electron diffraction tube
Article No:
06721-02
The electron diffraction tube enables the demonstration of the wave nature of electrons by observing interference patterns that become visible on the fluorescent screen after passing through a polycrystalline graphite lattice. The electron wavelengths can be determined as a function of the anode voltage using the diffraction rings and the lattice plane spacings of graphite, thereby experimentally confirming de Broglie’s hypothesis.
Key Features
- Highly evacuated tube for precise and reproducible experiments
- Direct observation of Debye–Scherrer diffraction on the fluorescent screen
- Precise control of the high voltage using a compatible power supply (06721-04)
