Aug 11, 2024 · Louis de Broglie (born August 15, 1892, Dieppe, France—died March 19, 1987, Louveciennes) was a French physicist best known for his research on quantum theory and for predicting the wave nature of electrons. He was awarded the 1929 Nobel Prize for Physics.
The Atomic Model. De Broglie’s wave-particle theory also contibuted to the Bohr model for the hydrogen atom. The Bohr model is a structural model of an atom, and electrons are visualized as circular orbits around the nucleus of the atom.
In his 1924 PhD thesis, he postulated the wave nature of electrons and suggested that all matter has wave properties. This concept is known as the de Broglie hypothesis, an example of wave–particle duality, and forms a central part of the theory of quantum mechanics.
The de Broglie‐Bohr model of the hydrogen atom presented here treats the electron as a particle on a ring with wave‐like properties. \[ \lambda = \frac{h}{m_e v} \nonumber \] de Broglie's hypothesis that matter has wave-like properties.
In 1924 Louis de Broglie introduced the idea that particles, such as electrons, could be described not only as particles but also as waves. This was substantiated by the way streams of electrons were reflected against crystals and spread through thin metal foils.
The Quantum–Mechanical Model of an Atom. Shortly after de Broglie published his ideas that the electron in a hydrogen atom could be better thought of as being a circular standing wave instead of a particle moving in quantized circular orbits, as Bohr had argued, Erwin Schrödinger extended de Broglie’s work by incorporating the de Broglie ...
Some thirty years ago, physics was hence divided into two: firstly the physics of matter based on the concept of corpuscles and atoms which were supposed to obey Newton’s classical laws of mechanics, and secondly radia-tion physics based on the concept of wave propagation in a hypothetical continuous medium, i.e. the light ether or electromagnet...
