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.

In simple terms, particles can also be expressed as waves. De Broglie’s generalization about wave-particle duality helped contribute to the universal atomic theory, and changed the study of quantum mechanics. The Atomic Model. De Broglie’s wave-particle theory also contibuted to the Bohr model for the hydrogen atom. The Bohr model is a ...
Louis de Broglie. Louis Victor Pierre Raymond, 7th Duc de Broglie ( / də ˈbroʊɡli /, [1] also US: / də broʊˈɡliː, də ˈbrɔɪ /, [2] [3] French: [də bʁɔj] [4] [5] or [də bʁœj] ⓘ; 15 August 1892 – 19 March 1987) [6] was a French aristocrat and physicist who made groundbreaking contributions to quantum theory. In his 1924 PhD ...
Louis de Broglie proposed that all particles could be treated as matter waves with a wavelength λ. . , given by the following equation: λ = h m v. Erwin Schrödinger proposed the quantum mechanical model of the atom, which treats electrons as matter waves. Schrödinger's equation, H ^ ψ = E ψ. .

Sep 12, 2022 · E = hf (6.6.1) λ = h p (6.6.2) Here, E and p are, respectively, the relativistic energy and the momentum of a particle. De Broglie’s relations are usually expressed in terms of the wave vector k , k = 2π/λ, and the wave frequency ω = 2πf, as we usually do for waves: E = ℏω p = ℏk. Wave theory tells us that a wave carries its energy ...
