Episode 505: Preparation for wave-particle duality topic

Teaching Guidance for 16-19 IOP TAP

As with quantum theory, this is a section of the course that candidates will find completely new.

Main aims of this topic

Wave particle duality


Students will:

  • understand that electron diffraction is evidence for wave-like behaviour
  • use the de Broglie equation
  • identify situations in which a wave model is appropriate, and in which a particle model is appropriate, for explaining phenomena involving light and electrons
  • use a standing wave model for electrons in an atom

Prior knowledge

Students should have an understanding of wave phenomena, including diffraction and interference. They should know how to calculate momentum.

This work follows on from a study of the photoelectric effect.

Where this leads

These episodes merely skim the surface of quantum physics. For students who wish to learn a little more, here is some suggested reading:

  • The New Quantum Universe; Tony Hey and Patrick Walters; CUP
  • Quantum Physics: An Introduction; J Manners; IOPP

You can extend the idea of electrons-as-waves further, to the realm of the atom.
