Electrons can behave like waves

Electrons can behave like waves

Schematic of an electron diffraction tube with electron gun, thin polycrystalline graphite, diffracted electron cones, and concentric rings on a fluorescent screen Wave-particle duality means a quantum object can show both particle-like and wave-like behaviour, depending on the experiment. Electrons arrive at a detector as localised impacts, so they are not just waves in the everyday sense.

  3. /Wave–particle duality

Step-by-step lessons on OCR A A Level Physics Wave–particle duality. Each one builds up to exam-style questions. Physics is one of the most mathematically demanding A Levels -- at least 40% of the marks across the three papers require maths skills at Level 2 (GCSE) standard or above, so build calculation and graph-handling fluency alongside the conceptual content from the start.
