De Broglie

Definition

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.

5 Must Know Facts For Your Next Test

1. Louis de Broglie introduced the theory of wave-particle duality in 1924.
2. 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.
3. This wave-particle duality was experimentally confirmed by electron diffraction experiments.
4. De Broglie's work earned him the Nobel Prize in Physics in 1929.
5. His hypothesis laid the groundwork for Schrödinger's wave equation.
