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.
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.
Atomic model, in physics, a model used to describe the structure and makeup of an atom. Atomic models have gone through many changes over time, evolving as necessary to fit experimental data. For a more in-depth discussion of the history of atomic models, see atom: development of atomic theory.
Although rejected by optics, the atomic theories began making great headway not only in chemistry, where they provided a simple interpretation of the laws of definite proportions, but also in the physics of matter where they made possible an interpretation of a large number of prop-erties of solids, liquids, and gases.
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.
One of the first people to pay attention to the special behavior of the microscopic world was Louis de Broglie. He asked the question: If electromagnetic radiation can have particle-like character, can electrons and other submicroscopic particles exhibit wavelike character?
We discuss the proposition of wave-particle duality made by Louis de Broglie in the period of 1922-1924 as well as the narratives of undergraduate Physics textbooks that introduce this topic.
