## de Broglie relation

[də¦brȯ¦glē ri′lā·shən]
(quantum mechanics)
The relation in which the de Broglie wave associated with a free particle of matter, and the electromagnetic wave in a vacuum associated with a photon, has a wavelength equal to Planck's constant divided by the particle's momentum and a frequency equal to the particle's energy divided by Planck's constant. Also known as de Broglie equation.

In quantum mechanics, momentum of microparticles p=mv, where m and v are respectively, the rest mass and the speed of the microparticles, with its wavelength [lambda] associated by de Broglie relation (p=h/[lambda]) .
The expression m[upsilon][lambda] = h used in (1) to arrive at the total electron kinetic energy is the de Broglie relation expressed in simple, physically intuitive terms: the de Broglie relation yields the product of the electron mass m, its average velocity [upsilon], and the path length [lambda] over which its instantaneous velocity varies.
