In General > s.a. scattering; wave
phenomena.
* Idea: The spreading of a wave interacting with a scatterer or slit;
In the context of semiclassical mechanics, it describes the manner in which
quantum
mechanics smooths over discontinuities in classical mechanics.
* History: In the 1660s,
Grimaldi observed an alteration of color
in shadows.
Special Effects > s.a. radiation;
Talbot Effect.
* Kapitza-Dirac effect:
The diffraction of a well-collimated particle beam by a standing wave of light;
There are plans to use it to build an electron
interferometer
10,000 times more sensitive than ones based on light.
