Many students interpret waveparticle duality to mean that electrons and photons follow a sinusoidal path
Quantum and Nuclear
Misconception

A lesson outline which can be used to compare the diffraction of electrons and light to introduce the idea of waveparticle duality. Particle momentum is linked to wavelength through the de Broglie equation.
Students can practice using the de Broglie equation and learn how to interpret electron diffraction patterns.
Use the lesson to explain the difference between the diagrams sometimes used to represent photons or electrons (wavy lines) to their actual straightline paths.
