THE WAVE NATURE OF MATTER
Describe the de Broglie hypothesis and the concept of matter waves.

WAVE-PARTICLE DUALITY: Light can be understood by a model where it is both a particle and a wave. DE BROGLIE HYPOTHESIS: All moving particles have wave properties and in particular a wavelength calculated from the de Broglie equation. Students should also be aware of wave–particle duality (the dual nature of both radiation and matter).

Outline an experiment to verify the de Broglie hypothesis.



A brief outline of the Davisson–Germer experiment will suffice.

Solve problems involving matter waves. For example, students should be able to calculate the wavelength of electrons after acceleration through a given potential difference.
