# de Broglie waves

- physics the set of waves that represent the behaviour of an elementary particle, or some atoms and molecules, under certain conditions. The de Broglie wavelength, λ, is given by λ = h/mv, where h is the Planck constant, m the mass, and v the velocity of the particleAlso called: matter waves
