Who discovered the wave-particle duality?

Question:

Who discovered the wave-particle duality?

A Concept of Quantum Physics:

The concept of wave-particle duality is a quantum physics concept that states that light and matter behave both as a wave and as a particle. This is seen at the subatomic level, but we do not perceive it in everyday life at the level of what appears to us as reality.

Answer and Explanation: 1

The concept of wave-particle duality was hypothesized by French physicist Louis de Broglie in 1923. However, this hypothesis was not supported by experiment until 1927, when Clinton Davisson and Lester Germer did an experiment involving the behavior of electrons on a nickel surface. This experiment showed the wave behavior of electrons, supporting de Broglie's wave-particle hypothesis.

Wave-particle duality means that light and sub-atomic particles can also behave as waves, hence the duality. Study the definition of wave-particle duality, the Davisson-Germer Experiment, the de Broglie wavelength, and an example calculation.
