Diffraction Patterns

Some articles on diffraction, diffraction patterns, patterns, pattern:

Fresnel Diffraction - Early Treatments of This Phenomenon
... work on what would become known as Fresnel diffraction was carried out by Francesco Maria Grimaldi in Italy in the 17th century ... MacLaurin explains Fresnel diffraction by asking what happens when light propagates, and how that process is affected when a barrier with a slit or hole in it is ... The result is that if the gap is very narrow only diffraction patterns with bright centers can occur ...
Crystallographic Database - Crystal Phase Identification - Lattice-fringe Fingerprinting (2D)
... Powder diffraction patterns of very small single crystals, or crystallites, are subject to size-dependent peak broadening, which, below a certain size, renders powder diffraction ... by applying single-crystal electron diffraction techniques ... High-Resolution Transmission Electron Microscopy (HRTEM) provides images and diffraction patterns of nanometer sized crystallites ...
Delayed Choice Quantum Eraser - The Experiment - Time Relations Among Data
... Only then will it become possible to see interference patterns in two groups and only diffraction patterns in the other two groups ... that in the schematic diagrams the fringes or interference patterns imaged by Detector 1 and Detector 2 will add together to form a solid band ... The addition of the diffraction patterns paired with the diffraction patterns seen by Detector 3 and Detector 4 will make the center area somewhat brighter than it ...
Low-energy Electron Diffraction - Theory of LEED - Interpretation of LEED Pattern - Domains
... An essential problem when considering LEED patterns is the existence of symmetrically equivalent domains ... Domains may lead to diffraction patterns which have higher symmetry than the actual surface at hand ... to the average domain size on the surface and hence the LEED pattern might be a superposition of diffraction beams from domains oriented along different axes ...

    Teasing is universal. Anthropologists have found the same fundamental patterns of teasing among New Zealand aborigine children and inner-city kids on the playgrounds of Philadelphia.
