'''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 [[Physics:Quantum mechanics|quantum mechanics]].<ref>{{cite web |url=https://www.nobelprize.org/prizes/physics/1929/broglie/biographical/ |title=Louis de Broglie - Biographical |publisher=Nobel Prize Outreach |access-date=20 May 2026}}</ref><br />
<br />
De Broglie's proposal was experimentally supported by electron diffraction and became deeply connected with the later development of the [[Physics:Quantum Wavefunction|wavefunction]]. His relation between momentum and wavelength helped explain why microscopic particles can display interference and diffraction while still being detected as localized events.<br />

== Matter waves ==<br />
The de Broglie wavelength links a particle's momentum with its associated wave character. This idea is central to [[Physics:Quantum Wave–particle duality|wave-particle duality]], [[Physics:Quantum Standing waves and modes|standing waves and modes]], and quantization in bound systems such as atoms.<br />
<br />
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.<br />
