Finally, because momentum p is equal to mass m times velocity v: \lambda = \frac {h} {p} λ = ph This is known as the de Broglie equation. As with any wavelength, standard unit of measure for the de Broglie wavelength is meters (m). de Broglie equation states that a matter can act as waves much like light and radiation, which also behave as waves and particles. The equation further explains that a beam of electrons can also be diffracted just like a beam of light. In essence, the de Broglie equation helps us understand the idea of matter having a wavelength.
