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.

www.khanacademy.org/science/physics/quantum-physics/.../de-broglie-wavelength The de Broglie wavelength, he figured it out, and he realized it was this. So, he actually postulated it. He didn't really prove this. He motivated the idea, and then it was up to experimentalists to try this out. So he said that the wavelength associated with things that we thought were matter, so sometimes these were called matter waves, but ...
• ## Thermal de Broglie wavelength - Wikipedia

en.wikipedia.org/wiki/Thermal_de_Broglie_wavelength In physics, the thermal de Broglie wavelength is roughly the average de Broglie wavelength of the gas particles in an ideal gas at the specified temperature. We can take the average interparticle spacing in the gas to be approximately (V/N) 1/3 where V is the volume and N is the number of particles. When the thermal de Broglie wavelength is much smaller than the interparticle distance, the gas ...

• ## Deriving the de Broglie Wavelength - Chemistry LibreTexts

chem.libretexts.org/Bookshelves/.../Deriving_the_de_Broglie_Wavelength The de Broglie wavelength is the wavelength, $$\lambda$$, associated with a object and is related to its momentum and mass. Introduction. 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.

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.
