The diffraction of light at the single slit can be explained by the Heisenberg uncertainty principle. The more the light path is narrowed, the wider the diffraction pattern of the slit appears on ...

The experiment showed that Bohr was definitely correct when he argued for complementarity, and that Einstein had got it wrong ...

Like the Play-Doh, each pulse that passes through the stencil does carry the whole "UR" shape, but, as with the two-slit diffraction pattern, one photon does not produce the whole image on being ...
