The double-slit experiment, first performed by [Thomas Young] in 1801 provided the first definitive proof of the dual wave-particle nature of photons. A similar experiment can be performed that shows ...

UV radiation from a relativistic electron beam is diffracted by a double-slit. In contrast to the normal light (left), the diffraction shows a deformation in the central part (right), indicating the ...

When waves – regardless of whether light or sound – collide, they overlap creating interferences. Austrian and Canadian quantum physicists have now been able to rule out the existence of higher-order ...
