It also explores how the alternative ring current model of an electron (or of matter-particles in general) relates to Louis de Broglie's λ = h/p relation and rephrases the theory in terms of the In this video I discuss the dispersion relation (variation of angular frequency and wave number) for De Broglie matter waves. This is part of my tutorial on In standard physics texts [5, p. 567], in order to apply the de Broglie relation, the following assumption is madeE 2 = |p| 2 c 2 + m 2 0 c 4 |p| 2 c 2 .(2)The notation is in accordance with previous articles by the author in this journal [6,8].From this equation the momentum of the electron is calculated as |p| = E/c, and from the de Broglie relation it follows that λ = hc/ E.Various explanations are given to support the … In both of them, I suppose you can use the de Broglie relations, but the actual underlying theory is totally different. $\endgroup$ – knzhou May 25 '16 at 4:07 $\begingroup$ knzhou is basically right. Two fundamental equations regarding wave-particle duality are: $$\lambda = \frac{h}{p}, \\ \nu = E/h .$$.

The derivation of De Broglie Wavelength of an Electron states the relation between matter and energy. To derivate the de Broglie wavelength of an electron equation, let’s take the energy equation which is. E = m.c 2. Here m = mass. E = energy. C = speed of light > Nature loves symmetry. This symmetric loving nature of Nature gave rise to de Broglie relation.

In his 1923 (or 1924, depending on the source) doctoral dissertation, the French physicist Louis de Broglie made a bold assertion. 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: According to de Broglie’s hypothesis, massless photons as well as massive particles must satisfy one common set of relations that connect the energy E with the frequency f, and the linear momentum p with the wavelength λ. We have discussed these relations for photons in the context of Compton’s effect. De Broglie was able to mathematically determine what the wavelength of an electron should be by connecting Albert Einstein's mass-energy equivalency equation (E = mc 2) with Planck's equation (E = hf), the wave speed equation (v = λf ) and momentum in a series of substitutions. de-Broglie Relation . The wavelength of the wave associated with any material particle was calculated by analogy with photon as follows :- In case of a photon, if it is assumed to have wave character, its energy is given by de Broglie's Justification of Bohr's Assumption.

### de broglie relation — Svenska översättning - TechDico

In order to overcome the imperfection of Bohr's atomic model, efforts were made to make a general model for atoms. 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.
