De broglie wavelength in terms of temperature

WebNov 6, 2024 · From this, using de Broglie's relation, we can define a typical thermal wavelength of atoms λ th = h p th = h 2 π m k B T where h is Planck's constant. This is the main quantity of interest here. This also serves as an estimate of the uncertainty in the atom's position. WebIn thermal equilibrium at (Kelvin) temperature T, the average kinetic energy of a particle is 3 pa 2m 3kB (where kp is Boltzmann's constant), so the typical de Broglie wavelength is h (1.45) 3mkoT The purpose of this problem is to determine which systems will have to be treated quantum mechanically, and which can safely be described classically.
