(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 ...

Silicon and carbon could explain Earth’s onion-like inner core
Deep beneath our feet, far beyond the reach of drills or submersibles, Earth hides a solid metal heart that behaves in ways geophysicists have struggled to explain. New experiments now suggest that a ...
The study of acoustic wave scattering and diffraction in waveguide structures lies at the forefront of both theoretical and applied acoustics. It encompasses the intricate processes by which sound ...
Google Earth provides a cornucopia of exotic images of our planet taken from above. For the most part, the focus of attention is on the land and the cities, roads and natural formations that it ...
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 ...
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 ...
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 ...
