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

GCSE Chemistry: Graphite Graphite is a form of carbon where each atom is bonded to three others in flat layers of hexagons. These layers are held together by weak forces, allowing them to slide over each other easily. This makes graphite soft and slippery, ideal for use in pencils and lubricants. It conducts electricity because it has free electrons that move between layers. #gcsechemistry #chemistry #science #gcserevision #chemistryrevision #gcsechemistryrevision #chemistryteachersofinstagram #

34K views · 297 reactions | Diamonds and graphite are both pure forms of carbon. So why are they so different?  X-ray crystallography allowed scientists to look at their atomic structure to understand their properties.
