De Broglie is known for proposing that particles, such as electrons, exhibit wave-like behavior. This concept is fundamental to the development of quantum mechanics.

Louis de Broglie introduced the theory of wave-particle duality in 1924.
De Broglie's hypothesis led to the formula $\lambda = \frac{h}{p}$, where $\lambda$ is the wavelength, $h$ is Planck's constant, and $p$ is momentum.
This wave-particle duality was experimentally confirmed by electron diffraction experiments.
De Broglie's work earned him the Nobel Prize in Physics in 1929.
His hypothesis laid the groundwork for Schrödinger's wave equation.
