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 equivalently written as 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. The de Broglie wavelength of a particle is inversely proportional to its momentum. The thermal de Broglie wavelength is roughly the average de Broglie wavelength of the gas particles in an ideal gas at the specified temperature. It is defined as (1) Λ = h 2 2 π m k B T In 1924 Louis de Broglie theorized that not only light posesses both wave and particle properties, but rather particles with mass - such as electrons - do as well. The wavelength of these 'material waves' - also known as the de Broglie wavelength - can be calculated from Planks constant h divided by the momentum p of the particle.

Mars- Louis de Broglie, fransk fysiker, nobelpristagare. At these temperatures, the thermal de Broglie wavelengths come into the micrometre range. Vid dessa  Taking the wavelength to be the de Broglie wavelength (λ = h/p), this becomes: 2πr = nh/p. The momentum (rörelsemängd), p, is simply mv as long as we're  owing to the smaller de Broglie wavelength of electrons. This enables the instrument to capture fine detail The minimum size of the wave function is given by the thermal de. Broglie wavelength, which has to be larger than the interparticle spacing to allow the quantum  Physics Page.

The thermal de Broglie wavelength (λ th) is approximately the average de Broglie wavelength of the gas particles in an ideal gas at the specified temperature. The thermal de Broglie wavelength is given by the expression: λ D = h / √ 2 π m k B T 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.
