Was hat de Broglie gemacht?
De Broglie gilt als einer der bedeutendsten Physiker des 20. Jahrhunderts, für seine Entdeckung der Wellennatur des Elektrons (Welle-Teilchen-Dualismus) in seiner Dissertation Recherches sur la théorie des quanta und der daraus resultierenden Theorie der Materiewellen erhielt er 1929 den Nobelpreis für Physik.
Was versteht man unter de Broglie Wellenlänge?
Die de Broglie Wellenlänge ist eine quantenmechanische Eigenschaft von Materieteilchen mit endlicher Ruhemasse, also zum Beispiel Elektronen oder Protonen. Photonen zeigen also sowohl Welleneigenschaften als auch Eigenschaften klassischer (Punkt-)Teilchen.
Who was Louis de Broglie and what did he do?
de Broglie wave Louis de Broglie, in full Louis-Victor-Pierre-Raymond, 7e duc de Broglie, (born August 15, 1892, Dieppe, France—died March 19, 1987, Louveciennes), 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.
What was the significance of the de Broglie hypothesis?
Significance of the de Broglie Hypothesis The de Broglie hypothesis showed that wave-particle duality was not merely an aberrant behavior of light, but rather was a fundamental principle exhibited by both radiation and matter.
When was the de Broglie diffraction pattern confirmed?
Experimental Confirmation In 1927, physicists Clinton Davisson and Lester Germer, of Bell Labs, performed an experiment where they fired electrons at a crystalline nickel target. The resulting diffraction pattern matched the predictions of the de Broglie wavelength.
How is the de Broglie wavelength related to its momentum?
According to wave-particle duality, the De Broglie wavelength is a wavelength manifested in all the objects in quantum mechanics which determines the probability density of finding the object at a given point of the configuration space. The de Broglie wavelength of a particle is inversely proportional to its momentum.
