La mécanique ondulatoire des systèmes de corpuscules - Louis de

Under utvecklingen av kvantmekaniken föreslog Louis de Broglie, i tre artiklar under 1923 och i sin doktorsavhandling 1924, [1] att våg-partikeldualiteten som påträffats för strålning skulle ha en motsvarighet för materia. The de Broglie equation shows that this wavelength is inversely proportional to both the mass and velocity of the particle (h is Planck's constant, 6.626x10-34 J. s). This explains why this wavelength is so small as to not be observable for large objects. In 1923, Louis de Broglie, a French physicist, proposed a hypothesis to explain the theory of the atomic structure. By using a series of substitution de Broglie hypothesizes particles to hold properties of waves. Within a few years, de Broglie's hypothesis was tested by scientists shooting electrons and rays of lights through slits.

Indeed, the momentum of a photon (i.e. the p we use in the Planck-Einstein relation) is not the momentum one associates with a proper particle, such as an electron or a proton, for example (so that’s the p we use in the de Broglie relation). Louis de Broglie stated that the standing waves produced by electrons has the relation with discrete wavelength.

The de Broglie relations. E/ħ = ω gives the frequency in time (expressed in radians per second), while p/ħ = k gives us the wavenumber, or the frequency in space (expressed in radians per meter). Of course, we may write: f = ω/2π and λ = 2π/k, which gives us the two de Broglie relations: De-broglie Relation : λ = p h ; this relation proposes that light has both wave-like and particle-like property. It basically establishes the wave-particle duality. 2019-01-01 De Broglie proposed that as light exhibits both wave-like and particle-like properties, matter to exhibit wave-like and particle-like properties.

The deBroglie Equation: Example Problems. Problem #1: What is the wavelength of an electron (mass = 9.11 x 10¯ 31 kg) traveling at 5.31 x 10 6 m/s? 1) The first step in the solution is to calculate the kinetic energy of the electron: KE = (1/2)mv 2. x = (1/2) (9.11 x 10¯ 31 kg) (5.31 x 10 6 m/s) 2 x = 1.28433 x 10¯ 17 kg m 2 s¯ 2 (I kept some guard digits) When I use this value just below While we were still struggling to understand this mystery, along came Louis de Broglie to make it even more complicated with his de Broglie Relation. De Broglie’s Equation De Broglie’s hypothesis stated that there is symmetry in nature and that if light and radiation behave as both particles and waves, matter too will have both the particle and wave nature. In this video you will learn how to calculate the wavelength of particles with the de Broglie relation. According to de Broglie, a moving material particle acts as a wave and sometimes wave is associated with moving material particle which controls the particle in every respect.
