Name the physicist associated with wave-particle duality

The physicist associated with the concept of wave-particle duality is Louis de Broglie. In 1924, de Broglie proposed that particles, such as electrons, exhibit wave-like properties, just as light exhibits both wave and particle characteristics. He introduced the idea that matter has a dual nature, with its wave behavior described by a wavelength known as the de Broglie wavelength, given by the equation λ=h/p, where h is Planck’s constant and p is the momentum of the particle.
De Broglie’s hypothesis was revolutionary and laid the foundation for quantum mechanics. It was later confirmed experimentally through the observation of electron diffraction, which demonstrated that electrons behave as waves under certain conditions. His work provided critical insights into the behavior of matter on atomic and subatomic scales and earned him the Nobel Prize in Physics in 1929.
