"de Broglie wavelength (L. de Broglie; 1924)"

Definition: de Broglie wavelength (L. de Broglie; 1924): The quantum mechanical "wavelength" associated with a particle, named after the scientist who discovered it. In quantum mechanics, all particles also have wave characteristics, where the wavelength of a particle is inversely proportional to its momentum and the constant of proportionality is the Planck constant.
