In the described picture the appearance of a de Broglie wave and the wave-particle duality are interpreted as a purely relativistic effect, arising as a consequence of the Lorentz transformation of the standing wave moving with the particle. {\displaystyle ~\lambda } is the period of oscillation of the de Broglie wavelength. Thus, we determine the main features associated with the wave-particle duality – if the energy of internal standing waves in the particles reaches the rest energy of these particles, then the de Broglie wavelength is calculated in the same way as the wavelength of photons at a corresponding momentum. Glencoe Physics: Principles and Problems, Student Edition. {\displaystyle ~p} From this we obtain the definition of the de Broglie wavelength through the Planck constant and the relativistic momentum of the particle: Unlike photons, which always move at the same velocity, which is equal to the speed of light, the momenta of the particles according to the special relativity depend on the mass Formula for de broglie wavelength in terms of kinetic energy Ask for details ; Follow Report by Gurpinderkaur1350 10.05.2019 Log in to add a comment and Completing the CAPTCHA proves you are a human and gives you temporary access to the web property. e Δ in the reference frame associated with the particle. Therefore, de Broglie wavelength is 1.09Ao . r {\displaystyle ~v} {\displaystyle ~r_{B}} Besides, in transitions from one orbit to another, which is closer to the nucleus, the electrons emit photons, which carry the energy But at the same time the electron’s excitation energy does not reach its rest energy, as it is required to describe the de Broglie wavelength in the forward motion of the particles. are the energy and momentum of the photon, To Calculate: The de Broglie wavelength of electron. Average kinetic energy of the neutron: Therefore, the de Broglie wavelength of the neutron is 0.146 nm. [6] e , and the formula (3) should hold for the angular momentum quantization in the hydrogen atom. • ℏ Δ E p Moreover, since the de Broglie wavelength behaves like the photon wavelength with the corresponding momentum, which unites particles and waves, de Broglie wavelengths are considered probability waves associated with the wave function. But in a mixed state, when the wave functions of several interacting particles are taken into consideration, the interpretation that connects the wave functions and probabilities becomes less accurate. E {\displaystyle ~c} will be to the In addition, in the article [7] is assumed that inside a particle there is a rotary electromagnetic wave. This is the result of the action of four approximately equal by magnitude forces, which arise from: 1) attraction of the electron to the nucleus due to strong gravitation and Coulomb attraction of the charges of electron and nucleus, 2) repulsion of the charged electron matter from itself, and 3) runaway of the electron matter from the nucleus due to rotation, which is described by the centripetal force. Cloudflare Ray ID: 5f8713ac88f7e73c π If you are at an office or shared network, you can ask the network administrator to run a scan across the network looking for misconfigured or infected devices. Light particles, like electrons, achieve more rapidly the velocity of the order of the speed of light, become relativistic and at low energies demonstrate quantum and wave properties. In 1924 a French physicist Louis de Broglie assumed that for particles the same relations are valid as for the photon: [1]. [3]. Δ {\displaystyle ~\hbar } {\displaystyle ~v} λ {\displaystyle ~n} 2 1 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. His particle wavelength equation is: λ … The motion of electrons in atoms occurs by means of rotation around the atomic nuclei. is the speed of light. c If the kinetic energy of an electron is increased by 9 times, de-Broglie wavelength associated with it would become A. de Broglie wavelength (λ) can be obtained by: Kinetic energy in terms of potential difference is, Therefore, de Broglie wavelength in terms of potential difference is, λ =6.6×10−342×9.1×10−31×1.6×10−19×125λ=1.09×10−10m =1.09Ao. h ℏ They can be electromagnetic waves or waves associated with the strong interaction of particles, with strong gravitation in the gravitational model of strong interaction, etc. At the same time, experiments with a set of particles cannot give an unambiguous value of the wavelength 2 ν where n 9 times B. L Boltzmann constant, k = 1.38 × 10 −23 kg m 2 s −2 K −1 . Δ {\displaystyle ~\nu } Instead, we obtain the relationship between the angular momentum and energy fluxes in the electron matter in stationary states and the change of these angular momenta and fluxes during emission of photons. {\displaystyle ~n} we will obtain the following: This corresponds to the postulate of the Bohr model, according to which the angular momentum of the hydrogen atom is quantized and proportional to the number of the orbit c . Δ The calculation provides the formula for the de Broglie wavelength, [2] [3] [4] = L
