We investigate qualitatively how diffraction affects sound waves of various frequencies. We also explore how constructive and destructive interference patterns are created and what that means for ...

Diffraction of a low frequency sound wave around a barrier. Note that the barrier does not create a sound shadow in the area of the lower right-hand corner. Barriers not built for acoustical purposes ...

IT has been well established1,2 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 ...

Sound, like light, can be tricky to manipulate on small scales. Try to focus it to a point much smaller than one wavelength and the waves bend uncontrollably--a phenomenon known as the diffraction ...

We have now observed for this small sound wave-length that, ... S., TIPNIS, C. Diffraction of Light by Ultrasonic Waves, Oblique Incidence and Sound Intensity. Nature 182, 1795–1796 ...

The diffraction limit is a fundamental constraint on using light or sound waves to image tiny objects. If the separation between two features is smaller than about half the wavelength of the light or ...

Editor's note: This article and the subsequent articles provide an introduction to Sound. It is excerpted from the book Audio in the 21st Century published by Intel Press. This excerpt is from Chapter ...

Sound is composed of particles moving in a continuous wave. Daniel A. Russell, CC BY-NC-ND. Controlling where sound goes is difficult because of a phenomenon called diffraction – the tendency of ...

To use their grating, Heyl and colleagues placed a pair of opposite-facing mirrors perpendicular to the standing ultrasound wave. A beam of light enters the device and is reflected back and forth many ...
