For 10 points, name this concept through which quantum-scale objects exhibit properties of both oscillations and single points of matter.
Both implications of this concept are considered under Niels Bohr's complementarity principle. This concept explains the result of an experiment in which electrons fired at a nickel crystal had a scattering pattern consistent with Bragg's law. This concept, which was confirmed by the Davisson-Germer experiment and generalized to all matter by de Broglie, accounts for the distinct ways that light behaves.

wave-particle duality [accept wave nature of electrons or any answer indicating that matter acts like a particle and a wave; accept de Broglie hypothesis before "de Broglie"]
