3.2.2.4 Wave-particle duality
| Content | Opportunities for skills development |
|---|---|
Students should know that electron diffraction suggests that particles possess wave properties and the photoelectric effect suggests that electromagnetic waves have a particulate nature. Details of particular methods of particle diffraction are not expected. de Broglie wavelength where is the momentum. |
Students should be able to explain how and why the amount of diffraction changes when the momentum of the particle is changed.
Appreciation of how knowledge and understanding of the nature of matter changes over time.
Appreciation that such changes need to be evaluated through peer review and validated by the scientific community.
