The corpuscular theory, which, at the time, was widely believed to describe correctly the propagation of light, could not explain diffraction. Huygens, the first proponent of the wave theory, seems to ...

A theoretical astrophysicist from the University of Kansas may have solved a nearly two-decade-old mystery over the origins ...

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 ...

A long-standing enigma surrounding the Crab Pulsar, a neutron star at the center of the Crab Nebula, may have been unraveled.

The goal of the current project is to open a new field of research by realizing the first diffraction experiments of atomic matter waves through crystalline 2D membranes like graphene. Such ...

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 ...

Several approaches are capable of beating the classical 'diffraction limit ... where evanescent waves have faded, cannot be far from that given by the well-known Abbe–Rayleigh rule, according ...

Medvedev’s research provides an explanation for the zebra pattern in Crab Pulsar’s high-frequency radio waves.

While shadow casting is based on light rays interacting with different geometries, diffraction casting is based on the ...

The diffraction limit is a fundamental barrier in optical microscopy that sets the minimum size of features that can be resolved using conventional light microscopes. It arises due to the wave nature ...
