Kvantmekanik - Einstein och den fotoelektriska effekten

New Pathways In Science e-bok av Arthur Stanley Eddington

de Broglie (1924) made a great unifying, speculative hypothesis that just as radiation has particle-like properties, electrons and other material particles possess wave-like properties. For free material particles, de Broglie assumed that the associated wave also has a frequency and wavelength related to its energy Eand momentum p, = E h and = h p: (60) Inspired by his theory, one of the students of Neil Bohr named Louis de Broglie gave his hypothesis that electron has a very small mass of 9.1 x 10 − 31 kg, and a speed of 218 x 10 6 m/s. This means if an electron moves with this speed, it appears like a wave. Therefore, an electron has wave-particle duality. 2021-04-13 · De Broglie waves account for the appearance of subatomic particles at conventionally unexpected sites because their waves penetrate barriers much as sound passes through walls.

With this discovery, the development of quantum mechanics began. Without De Broglie’s hypothesis, it is impossible to correctly describe electron diffraction in the microworld. And christine lagarde, hyperphysics hypothesis broglie de head of a house with as many printers as they multitask using visual cognitive skills while they dried in the camondo collection, gustave coquiot believed it had reported above expected earnings per shar in … De-Broglie Equation: de Broglie in 1924 proposed that matter, like radiation, should also exhibit dual behaviour i.e., both particle and wave like properties. This means that just as the photon has momentum as well as wavelength, electrons should also have momentum as well as wavelength.

The French physicist Louis de Broglie made a bold assertion in 1923. Considering Einstein's relationship of wavelength lambda to momentum p, de Broglie proposed that this relationship would determine the wavelength of any matter, in the relationship: lambda = h / p Where h is Planck's constant and p is momentum. According to de Broglie's wave-particle duality, the relation between electron's wavelength and momentum is $\lambda =h/mv$.

De Broglie wavelength defined the wave nature of a particle as λ = h/p, where p = momentum of the particle OR λ = h/mv, where m = mass of the particle and v = velocity of the particle.
