Louis de Broglie (15 August 1892 - 19 March 1987) was a French physicist who introduced the idea that matter has wave-like properties. His doctoral thesis proposed that particles such as electrons are associated with waves, extending the wave-particle duality of light to material particles. This matter-wave hypothesis became one of the starting points for modern quantum mechanics.[1]
De Broglie's proposal was experimentally supported by electron diffraction and became deeply connected with the later development of the wavefunction. His relation between momentum and wavelength helped explain why microscopic particles can display interference and diffraction while still being detected as localized events.
Matter waves
The de Broglie wavelength links a particle's momentum with its associated wave character. This idea is central to wave-particle duality, standing waves and modes, and quantization in bound systems such as atoms.
De Broglie also developed pilot-wave ideas, an attempt to describe particle motion guided by an underlying wave. Although this approach was not the mainstream Copenhagen interpretation, it later influenced hidden-variable and realist approaches to quantum theory.
