New analysis rescues quantum wave-particle duality

dual-slit experiment

The presence of two slits in a barrier allows light waves passing through to interfere, creating an interference pattern of light and dark bands on a detector screen. Particles, such as electrons, also exhibit such interference and so also behave as waves. But with only one slit in the barrier, both light and electrons behave as particles, producing no interference pattern. This principle of wave-particle duality has been challenged, but a new analysis reaffirms it.
