... The wave-particle duality is fundamental to quantum mechanics. Light can behave like a particle (photon); matter can behave like a wave. The wavelength associated with a particle is inversely proportional to its momentum p: λ = h / p, where h is Planck’s constant. For cold atoms, the wavelength is l ...
