• ## Matter wave - Wikipedia

en.wikipedia.org/wiki/Matter_wave The de Broglie wavelength is the wavelength, λ, associated with a massive particle (i.e., a particle with mass, as opposed to a massless particle) and is related to its momentum, p, through the Planck constant, h: = =.

www.khanacademy.org/science/physics/quantum-physics/.../de-broglie-wavelength Instead what we do is to use electrons. Since electrons have a rest mass, unlike photons, they have a de Broglie wavelength which is really short, around 0.01 nanometers for easily achievable speeds. This means that a microscope using electron "matter waves" instead of photon light waves can see much smaller things.

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.

What is the magnitude of the velocity of this electron? Answer: The magnitude of the velocity of this electron can be found by rearranging the de Broglie wavelength formula.
• ## 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 ...

hyperphysics.phy-astr.gsu.edu/hbase/quantum/debrog2.html DeBroglie Wavelength A convenient form for the DeBroglie wavelength expression is where hc = 1239.84 eV nm and pc is expressed in electron volts. This is particularly appropriate for comparison with photon wavelengths since for the photon, pc=E and a 1 eV photon is seen immediately to have a wavelength of 1240 nm.

www.thoughtco.com/definition-of-de-broglie-equation-604418 The de Broglie equation is an equation used to describe the wave properties of matter, specifically, the wave nature of the electron: λ = h/mv, where λ is wavelength, h is Planck's constant, m is the mass of a particle, moving at a velocity v. de Broglie suggested that particles can exhibit properties of waves.
