| 单词 | de Broglie wavelength |
| 释义 | de Broglie wavelength The wavelength of the wave associated with a moving particle. The wavelength (λ) is given by λ = h/mv, where h is the Planck constant, m is the mass of the particle, and v its velocity. The de Broglie wave was first suggested by Louis de Broglie in 1924 on the grounds that electromagnetic waves can be treated as particles (photons) and one could therefore expect particles to behave in some circumstances like waves (see complementarity). The subsequent observation of electron diffraction substantiated this argument and the de Broglie wave became the basis of wave mechanics |
