(PhysOrg.com) -- When trying to focus sound waves into as small an area as possible, scientists run into a fundamental limit called the diffraction limit. That is, when sound waves are focused into a ...

Diffraction is a fundamental wave phenomenon. It manifests itself for light waves in almost all optical systems, limiting our ability to focus or collimate light beams. Due to diffraction, it is ...

Waves of all types inevitably spread out while propagating, owing to diffraction. Under certain strict conditions, however, waves can be made to propagate without diffraction. Although this has been ...

Diffraction phenomena are of fundamental importance for the characterization and analysis of materials in industrial and scientific applications. Prominent examples include X-ray crystallography as ...

CHAMPAIGN, Ill. -- A new imaging technique that uses electron diffraction waves to improve both image resolution and sensitivity to small structures has been developed by scientists at the University ...

Difference between Interference and Diffraction: This article covers an important topic from Class 12 Physics. As we all know, Physics is one of the toughest subjects in Class 12. With the vast amount ...

SIAM Journal on Applied Mathematics, Vol. 48, No. 1 (Feb., 1988), pp. 1-37 (37 pages) We derive an asymptotic partial differential equation which describes the diffraction of a weakly nonlinear high ...

The first neutron interferometer built from two separate crystals rather than one could lead to more advanced measurements of quantum effects, including in gravitational fields. Developed by ...
