What experiment did Louis De Broglie do?

Answer 1

Louis de Broglie did not conduct a specific experiment but rather proposed a groundbreaking hypothesis in his 1924 doctoral thesis, suggesting that particles, such as electrons, exhibit wave-like properties, a concept known as wave-particle duality. This idea was supported by later experiments, such as the double-slit experiment, which demonstrated the wave behavior of electrons. De Broglie's work laid the foundation for quantum mechanics and earned him the Nobel Prize in Physics in 1929. His hypothesis fundamentally changed the understanding of the nature of matter and light.
