This view, which is now universally accepted, is the foundation of fwave mechanics', the modern theory of interatomic effects. It predicts that electrons should show diffraction effects with ...

For a long time it was thought that diffraction effects made it impossible for lasers and other photonic devices to be smaller than about half the wavelength of the light they emitted or processed.

Such patterns are central to understanding the diffraction limit, a natural effect that sets a boundary on the smallest details that conventional optical microscopes can resolve. (Image: adapted from ...

The waves always 'spread' to some extent into the area beyond the gap. This is diffraction - the spreading out of waves when they go through a gap, or past the edge of a barrier. The extent of the ...
