More recent experiments have succeeded in suspending a single luminous pulsating bubble in a standing wave acoustic field, visible in an undarkened room. Generally sonoluminescence is light emission from small cavitating bubbles of air or other gas in water or other fluids, produced when the fluid is acted upon by intense high frequency sound waves. The mechanism is not completely understood, but very high pressures and temperatures are thought to be produced at the centre of the collapsing bubbles.
A New Hypothesis On The Mechanism Of Sonoluminescence It is hypothesized that sonoluminescence is due to the collision of this jet with the other side of the bubble surface. The mechanism of light emission is a http://flux.aps.org/meetings/YR9596/BAPSDFD96/abs/S220008.html

Stephen Caesar's Articles Known as sonoluminescence, this conversion of sound into light occurs during the rapid and violent contraction of the bubble as it oscillates in step with http://www.creationism.org/caesar/sonoluminescence.htm
Extractions: (This article may be copied for educational purposes only.) "Light before Stars?" Genesis 1:3 states, "And God said, Let there be light: and there was light." Critics have made the claim that, since stars were not created until verse 16, verse 3 must be in error. After all, how could light come into existence if stars - the very things that create light - had not yet been created? A closer examination of verse 3, combined with very recent scientific discoveries, may well provide the answer. According to a careful reading of verse 3, light was created as the result of God's voice: "And God said, Let there be light." Modern science has demonstrated that light can be produced purely from sound, and not exclusively from light-giving sources such as stars. Physicists Keith Weninger, Seth J. Putterman, and Bradley P. Barber of the University of California at Los Angeles performed a remarkable experiment that has confirmed the existence of sonoluminescence - light that is created from sound.

Extractions: Sonoluminescence is the process of converting sound into light. There are two types of sonoluminescence, Multiple Bubble Sonoluminesence (MBSL) and Single Bubble Sonoluminescence (SBSL). In order to perform sonoluminescence, a flask full of water or whatever medium is connected to two piezoelectric transducers (used to amplify sound). The amplifiers feed into the transducers which then start emitting a very concentrated amount of sound, usually around 20-35 Khz. At this point in time, bubbles begin to form, dubbed as "cavitation bubbles." Once a cavitation bubble is captured in the middle of the flask, it is under the effects of the amplified sound. At a certain resonance point, the bubble begins to emit flashes of white light.
Chemical Communications Articles sonoluminescence quenching by organic acids in aqueous solution pH and frequency effects. Gareth J Price, Muthupandian Ashokkumar, Timothy D Cowan, http://xlink.rsc.org/?DOI=b201795d
Extractions: The current status of knowledge of the sonoluminescence mechanism is reviewed. It is shown that the origin of sonoluminescence in multibubble cavitation fields is best described by the local charging theory of cavitation bubbles. For certain acoustic field configurations, a single stably pulsating cavitation bubble develops, which differs from its 'ordinary' counterparts in a number of respects, and whose sonoluminescence is a thermal effect in contrast to the luminescent glow of the ensemble of 'cold' cavitation bubbles. A model of single-bubble sonoluminescence is proposed, which includes the additional resonance absorption of energy by a solitary cavitation bubble in a symmetric acoustic field. The mechanisms of some single-bubble effects are as yet not clear. Full-text: pdf (435 Kb)

Extractions: Homepage Microbial Bioremediation Cavitation and Sonoluminescence Iodine Is Water Ever Safe to Drink The Water Business Some visions for improving water quality disappear like the bursting of a bubble, like a flash of insight that goes dark in the face of practical application. For others, the bubble itself is the key to purifying water, including the flashes of light that are emitted when ultrasound-generated cavities collapse. Introduction to Cavitation The formation in water of small bubbles is called cavitation and the bubbles themselves are cavities in the water. The most common example is when water boils at 100 degrees Celcius: pockets of vapor form then rapidly collapse, producing an audible sound. The cavities originate on a surface such as the sides of the container, impurities in the water, or other irregularities. Water boils when the vapor pressure in the water is greater than the local ambient pressure. Cavitation also occurs when the local ambient pressure falls below the vapor pressure. Cavitation can be produced by heat, light (lasers), ultrasound, and/or mechanical action (propellers, pumps, etc.).
