square of the amplitude of a matter wave gives the probability of finding a particle at a given place. Louis occasionally joined his brother in his work, but it was the purely conceptual side of physics that attracted him. For about three decades after his work of 1923, de Broglie held the view that underlying causes could not be delineated in a final sense, but, with the passing of time, he returned to his earlier belief that the statistical theories hide a completely determined. The De Broglie Equations, the de Broglie equations relate the wavelength to the momentum ( p), and the frequency ( f) to the kinetic energy (. Germer fired slow-moving electrons at a crystalline nickel target. It is now an integral part of the theory of atomic structure and particle physics. Further experiments have held de Broglie's hypothesis to be true, including the quantum variants of the double slit experiment. De Broglies suggestion, his one major contribution to physics, thus constituted a triumph of intuition. 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.

The first publications of de Broglies idea of matter waves had drawn little attention from other physicists, but a copy of his doctoral thesis was sent to Einstein, whose response was enthusiastic. See de Broglie wave.) The notion that matter on the atomic scale might have the properties of a wave was rooted in a proposal Einstein had made 20 years before. In many ways light acts as a wave, with a characteristic frequency, wavelength, and amplitude. He also acted, after 1945, as an adviser to the French Atomic Energy Commissariat. De Broglie concluded that most particles are too heavy to observe their wave properties.

De Broglie's Thesis, in his 1923 (or 1924, depending on the source) doctoral dissertation, the French physicist Louis de Broglie made a bold assertion. Thus, the de Broglie equation suggests that the wavelength ( ) of any object in motion is inversely proportional to its momentum. He described himself as having much more the state of mind of a pure theoretician than that of an experimenter or engineer, loving especially the general and philosophical view. The angular dependence of the reflected electron intensity was measured and was determined to have the same diffraction pattern as those predicted by Bragg for X-rays. It also provided a basis for understanding why this model failed for more complex systems. Maurice, who was also a physicist and made notable contributions to the experimental study of the atomic nucleus, kept a well-equipped laboratory in the family mansion in Paris. E should be total energy, kinetic energy, or total relativistic energy. Therefore, the presence of any diffraction effects by matter demonstrated the wave-like nature of matter. He was a foreign member of the British Royal Society, a member of the French Academy of Sciences, and, like several of his forebears, a member of the Acadmie Franaise.

De Broglie applied his theory of wave-particle duality to the Bohr model to explain why only certain orbits are allowed for the electron. De Broglies interest in what he called the mysteries of atomic physicsnamely, unsolved conceptual problems of the sciencewas aroused when he learned from his brother about the work of the German physicists. Terms wavelengthThe distance between one peak or trough of a travelling oscillation and the next; it is often designated in physics as and corresponds to the velocity divided by the frequency.
