E.2.4 (HL)—Particle diffraction Topic Practice
E.2.4 (HL)—Particle diffraction Topic Practice
Use diffraction evidence to identify electrons as matter waves and separate true wave evidence from unrelated particle results.
How this is tested
- choose electron diffraction by a crystal or slits as wave evidence, not alpha-scattering results
- use a diffraction pattern or intensity minimum on a graph to argue that electrons show wave behaviour
