Now, two unrelated-but-similar experiments confirm that, in a double-slit experiment, detection of a photon’s path (its particle nature) would wash out its interference pattern (its wave nature), proving Bohr right. The matter in question was the idea of “complementarity,” which stated (in simple terms) that a photon’s particle and wave nature can’t be measured at the same time. particle nature), the lower the visibility of the interference pattern (i.e. wave nature). The team then used lasers and electromagnetic forces to control the atom’s quantum properties and scattered light in two directions.
