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]].&lt;ref&gt;{{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}}&lt;/ref&gt;<br /> <br /> De Broglie&#039;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 /> <br /> == Matter waves ==<br /> The de Broglie wavelength links a particle&#039;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 /> <br /> == See also ==<br /> * [[Physics:Quantum Wave–particle duality]]<br /> * [[Physics:Quantum Wavefunction]]<br /> * [[Physics:Quantum Boundary conditions and quantization]]<br /> * [[Physics:Quantum Hidden variable theory]]<br /> <br /> == References ==<br /> {{reflist|3}}<br /> <br /> {{DEFAULTSORT:Broglie, Louis de}}<br /> [[Category:Nobel laureates in Physics]]<br /> [[Category:Quantum physicists]]<br /> [[Category:Theoretical physicists]]<br /> <br /> {{Sourceattribution|Biography:Louis de Broglie|1}}</div>
