The electron diffraction tube demonstrates the wave nature of electrons, supporting the de Broglie hypothesis. In this setup, a heated cathode emits electrons, which are then accelerated by a high voltage (around 4–6 kV) toward a thin graphite film. Graphite, made of regularly spaced carbon atoms, acts like a diffraction grating. As the high-speed electrons pass through the graphite, they diffract due to their wave-like behavior. This diffraction produces a series of concentric rings on a fluore
