By the de Broglie hypothesis, we see that

After his PhD de Broglie remained at the Sorbonne in Paris, becoming professor of Theoretical Physics Institute Henri Poincare in 1928. He taught until 1962. In 1945 he became advisor to the French Atomic Energy Commissariat. De Broglie’s theory on the problem of electron waves was later used by Schrodinger to discover the mechanical waves. De Broglie received the Award Nobel in 1929.

Matter and wave–particle duality[edit source | editbeta] Main article: De Broglie hypothesis

The de Broglie hypothesis [ edit ]

de Broglie assumed that because light had both particle and wave properties, that this may also be true for matter. Thus he was not actually looking for the wave structure of matter. Instead, as matter was already assumed to be a particle, he was looking for wave properties of matter to complement the known particle properties. As a consequence of this particle/wave duality, de Broglie imagined the standing waves to be related to discrete wavelengths and standing waves for certain orbits of the electron particle about the proton. (Rather than considering the actual standing wave structure of the electron itself.)

Early Life. Louis-Victor de Broglie was the son of Victor, duc de Broglie, and Pauline d’Armaillé; he was the younger of two brothers in a family of five children. His family, from a noble Italian (Piedmont) lineage, the Broglia, settled in France when Francesco Maria Broglia followed Cardinal Jules Mazarin in the seventeenth century. After that time, the family served the French kings and then the French state in military and diplomatic affairs. With the brothers Maurice and especially Louis, it added to its famous representatives (among them three state marshals) two world-rank physicists of the twentieth century.

From de Broglie's perspective, and from modern physics at that time, this solution had a certain charm. It maintained the particle - wave duality for BOTH light and matter, and at the same time explained why only certain orbits of the electron (which relate to whole numbers of standing waves) were allowed, which fitted beautifully with Niels Bohr model of the atom. de Broglie further explains his reasoning for the particle/wave duality of matter in his 1929 Nobel Prize acceptance speech;From a theoretical perspective, electron diffraction clearly portrays the accuracy of de Broglie's wave theory. Experimental confirmation of this theory is crucial in physics because the de Broglie wave theory is really the basis of quantum/wave mechanics. In this experiment, entities which have classically been considered particles, electrons, clearly behaved like waves. In his doctoral in 1924, Louis de Broglie developed the equation = h/m, which predicts that the wavelength of a particle is inversely proportional to its mass m and velocity where h is Planck's constant. The wavelength associated with a submicroscopic objectan electron, for exampleis large relative to the size of the object and is therefore significant in describing its behavior, whereas the wavelength associated with a macroscopic objecta basketball, for exampleis negligibly small relative to its size, and therefore the wavelike behavior of such an object is unnoticeable.De broglie thesis number of pages.

Louis de Broglie was the sixteenth member elected to occupy of the in 1944, and served as Perpetual Secretary of the . De Broglie became the first high-level scientist to call for establishment of a multi-national laboratory, a proposal that led to the establishment of the European Organization for Nuclear Research ().

De Broglie’s keen interest in the philosophical of modern physics found expression in addresses, articles, and books. The central question for him was whether the statistical considerations that are fundamental to atomic physics reflect an ignorance of underlying causes or whether they express all that there is to be known; the latter would be the case if, as some believe, the act of measuring affects, and is inseparable from, what is measured. For about three decades after his work of 1923, de Broglie held the view that underlying causes could not be in a final sense, but, with the passing of time, he returned to his earlier belief that the statistical theories hide “a completely determined and ascertainable reality behind variables which elude our experimental techniques.”

In 1929, de Broglie won the Nobel Prize in physics for his discovery of the wave nature of electrons

This effect has been used to demonstrate atomic , and it may allow the construction of with nanometer resolution. The description of these phenomena is based on the wave properties of neutral atoms, confirming the de Broglie hypothesis.
