The wavelength of a particle, given by \lambda = {h\over p}, where h is Planck's constant and p is the momentum. In the nonrelativistic limit, this can be written \lambda={h\over mv}, where m is the particle mass and v is the velocity. See also: de Broglie Wavenumber

De Broglie-hypotesen föreslår att all materia uppvisar vågliknande egenskaper och relaterar de observerade våglängd av materia till dess fart.

The De Broglie Equations. The de Broglie equations relate the wavelength (λ) to the momentum (p), and the frequency (f) to the kinetic energy (E) (excluding its rest energy and any potential energy) of a particle: [latex]\lambda ={ h }/p[/latex] and [latex]f={ E }/{ h }[/latex] where h is Planck’s Constant. The two equations can be The obtained wavelength is nothing but the Compton wavelength in the Compton effect with correction for the Lorentz factor.. 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. The de Broglie wavelength is the wavelength, \(\lambda\), associated with a object and is related to its momentum and mass. Introduction By using a series of substitution de Broglie hypothesizes particles to hold properties of waves.

Electron waves can also have any wavelength λ λ . It turns out that this wavelength depends on how much momentum the  Example 1: Calculate the de Broglie wavelength for an electron that is accelerated inside a potential difference of 150 volts. Solution: Using the above formula, we  For an ensemble of photons taken collectively, the de Broglie wavelength is λ/N, the wavelength of an individual photon divided by the number of photons. This  The electron has the longer de Broglie wavelength.

½ mv 2 = eV. v = 2eV / rt(m) The de Broglie wavelength is According to de Broglie's wave-particle duality, the relation between electron's wavelength and momentum is $\lambda =h/mv$. The proof of this is given in my textbook as follows: De Broglie first Its de-Broglie wavelength will be; λ = h/mv = [(6.626 x 10-34 kgm 2 s-1) / (10-2 kg ×10 2 ms-1)] = 6.62 x 10-34 m.

de Broglie wavelength in different frames. Course Home equation for it. So it's a wave of what? he was asking-- de Broglie had little idea what that wave was.

Introduction By using a series of substitution de Broglie hypothesizes particles to hold properties of waves. The de Broglie wavelength will be equal t o λ C = h /m c for v = c: 2. We can now relate both Compton as well as de Broglie wavelengths to our new wavelength λ = β·λ C De Broglie wavelength The wavelength γ = h / p associated with a beam of particles (or with a single particle) of momentum p ; h = 6.626 × 10 34 joule-second is Planck's constant. The same formula gives the momentum of an individual photon associated with a light wave of wavelength γ.

The de Broglie wavelength of an electron, however, is a significant value in describing what electrons do, since the rest mass of an electron is small enough to put it on the quantum scale.

(This is why the limiting resolution of an electron microscope is much higher than that of an optical microscope.) The wavelength of a particle, given by \lambda = {h\over p}, where h is Planck's constant and p is the momentum. In the nonrelativistic limit, this can be written \lambda={h\over mv}, where m is the particle mass and v is the velocity. See also: de Broglie Wavenumber De Broglie proposed the following relation, in which the wavelength of the electron depends on its mass and velocity, with h being Planck’s constant. The greater the velocity of the electron, the shorter its wavelength.

L = h / (m*v) Where L is the wavelength; h is Plank’s constant (6.6262 X 10 & -34 Js) De Broglie wavelength is the wavelength associated with a matter wave. Matter, though it can behave like particles, also behaves like a wave. Both light and matter behave like a wave on a large scale and like a particle on a small scale. To calculate the matter wave, we use the formula de broglie wavelength = planck's constant / momentum. What is the de-Broglie wavelength associated with (a) an electron moving with speed of `5.4xx10^6ms^-1`, and (b) a ball of mass 150g traveling at `30.0ms^-1`?
