2020年10月6日 · De Broglie's argument might be simplified to say that for a particle at rest, there is an associated wave with frequency f=E/h=mc^2/h, where m is the rest mass, E is the rest energy. The wave is a standing wave in this frame of reference since all of space vibrates at that rate with no change in phase with distance (the wave vibrates only with ...

2019年12月25日 · L. de Broglie, “Recherches sur la théorie des quanta”, Thèse de doctorat soutenue à Paris, le 25 novembre 1924, Annales de Physique (10e série) III (1925) 22. Reproduced in: L. de Broglie, Recherches sur la théorie des quanta (Fondation Louis de Broglie, Paris, 1992). I've searched online for that document, and I can't find it.

In 1924, Louis de Broglie postulated that particles such as electrons and protons might exhibit wavelike properties. His thinking was guided by the notion that light has both wave and particle characteristics, so he postulated that particles such as electrons and protons would obey the same wavelength-momentum relation as that obeyed by light ...

Using the given equation, calculate the de Broglie wavelength of a helium nucleus (mass = 6.7 x 10^-27 kg) moving with a speed of 2.0 x 1. Louis de Broglie extended the idea of wave-particle duality to all of nature with his matter-wave equation, λ = h/mv, where λ is the particle's wavelength, m is its mass, v is its velocity, and h is Planck ...

Louis de Broglie postulated that the wavelength of an electron is given in terms of Planck’s constant and its momentum, l = h/p. c. The amplitude of a wave function at a particular point in space equals the probability density of finding the electron at that point.

2023年1月12日 · $\begingroup$ @RogerVadim De Broglie was close to be a double nobel laureate: "In 1936, de Broglie, with his usual gift for spotting the obvious, articulated what was becoming apparent to many physicists: for every particle there is a corresponding antiparticle with opposite quantum numbers."

2.7 An Equation for de Broglie's Matter Waves. In $ 2.6, we discussed the hypothesis of the irrepressible Prince Louis de Broglie, who in his Ph. D. thesis maintained that all matter has wave-like properties--so that, for example, material particles should display diffraction phenomena when they interact with objects whose size is of the order of the particle's wavelength.

A. Find the de Broglie wavelength λ for an electron moving at a speed of 1.00×106m/s. (Note that this speed is low enough that the classical momentum formula p=mv is still valid.) Recall that the mass of an electron is me=9.11×10−31kg, and Planck's constant is h=6.626×10−34J⋅s.

The hypothesis that was put forward by Louis de Broglie in 1924 was astonishing for a number of reasons. An obvious reason is that associating a wavelike nature with particles is far from intuitive, but another astonishing aspect was how well the hypothesis fit …
