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 ...

Proceedings of the Royal Society of London. Series A, Mathematical and Physical Sciences, Vol. 209, No. 1096 (Oct. 8, 1951), pp. 81-96 (16 pages) The radio waves from 'radio stars' may suffer ...

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 ...

IT has been well established 1,2 that, in the case of diffraction of light by very-high-frequency sound waves only the first order of diffraction appears in the field of view and it attains the ...

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 ...

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 of Illinois at ...

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 ...

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 ...

sound waves cause air particles to vibrate back and forth ripples cause water particles to vibrate up and down Waves cause a disturbance of the medium through which they travel. This allows them to ...
