In 1924, de Broglie proposed his famous hypothesis that all matter, including electrons, exhibits both wave-like and particle-like properties. This was a revolutionary idea that helped to lay the foundation for quantum mechanics.
Here's a brief summary:
* Particle-wave duality: This principle states that light and matter can behave like both waves and particles.
* De Broglie's hypothesis: He suggested that the wavelength of a particle is inversely proportional to its momentum. This means that a particle with a higher momentum has a shorter wavelength.
* Experimental confirmation: De Broglie's hypothesis was later confirmed by experiments like the Davisson-Germer experiment (1927), which showed that electrons diffract like waves when passing through a crystal lattice.
De Broglie's work was groundbreaking and earned him the Nobel Prize in Physics in 1929.
