Sonoluminescence is the emission of short bursts of light from imploding bubbles in a liquid when excited by sound Table of contents showTocToggle("show","hide") 1 History 2 Properties 3 Theories 4 Shrimpoluminesence ... 7 External links History The effect was first discovered at the University of Cologne in as a result of work on sonar . H. Frenzel and H. Schultes put an ultrasound transducer in a tank of photographic developer fluid. They hoped to speed up the development process. Instead, they noticed tiny dots on the film after developing, and realized that the bubbles in the fluid were emitting light with the ultrasound turned on. It was too difficult to analyze the effect in early experiments because of the complex environment of a large number of short-lived bubbles. More than 50 years later, in 1989, a major advancement in research was introduced by Felipe Gaitan (or Felip Caitan ) and Lawrence Crum , who were able to produce single bubble sonoluminescence (SBSL). In SBSL, a single bubble, trapped in the acoustic standing wave, emits a pulse of light with each compression of the standing wave. This technique allowed a more systematic study of the phenomenon, because it isolated the complex effects into one stable, predictable bubble. They realized that the temperature inside the bubble was hot enough to melt steel. Interest in sonoluminescence was renewed when an inner

Next: THEORETICAL MATERIALS PHYSICS Up: ACOUSTICS Previous: Surface-Acoustic Waves Sonoluminescence (A. Särkilahti and M. M. Salomaa) An intense field of ultrasound in a fluid can trap a sub-millimeter radius gas bubble and make it emit light. This phenomenon is called sonoluminescence. The mechanisms that convert sound into light still remain unexplained despite many various theoretical approaches. A gas bubble is created into a flask filled with fluid. For example degassed, purified water and air are an excellent pair for the phenomenon. A coherent beam of ultrasound makes the bubble cavitate, i.e. to expand and compress in phase with the sound wave. Typical frequency for the sound wave is 25 kHz. While violently imploding in each cycle, the bubble emits light quanta. The duration of the light pulses is less than 50 ps and their energy is about 3 eV. The intensity of the acoustic field is thereby amplified by a factor of Figure 5.12: Motion of the sonoluminescence bubble as a function of time. Notice the supersonic velocity of the radius at the time of imploding. The source of the sonoluminescence light is unknown. The duration of the light pulses is shorter than the electromagnetic transitions in atoms. The exact motion of the bubble cannot be described with classical hydrodynamics, instead the so-called Rayleigh-Plesset equation must be used. The proposed explanations for the phenomenon contradict each other. These vary from shock waves produced into the bubble to quantum vacuum radiation.

Sonoluminescence, Quotes and Links~ Hello, my name is Chris Petersen. I am a Physics major at the University of California Santa Barbara and no longer at Shasta College in Redding, CA. While at Shasta College I completed an independent study on single bubble Sonoluminescence (SBSL). Under Tom Masulis and Joe Polen, Douglas Manning and I were successful in making Sonoluminescence. This is an incredible phenomenon where sound can be converted into light! Sonoluminescence was discovered by accident (like most applications in science) in the early 1930's by a pair of German Physicists @ the University of Cologne. It hasn't been until the last ten years that theorists and researchers have really given sonoluminescence an audience. The leading work has being done by Seth J. Putterman, Robert A. Hiller and Bradley P. Barber at UCLA. While this group has published many papers on sonoluminescence the most popular of their papers can be found in Scientific American Feb. 1995 Vol.272. The phenomenon of single bubble sonoluminescence can be produced as a table top physics project. From 100 to 200 dollars one can make sonoluminescence. To make SBSL (Single Bubble Sonoluminescence) one has to have a bubble (of plain air) surrounded by water in a spherical flask and then bombarded by high frequency sound waves. This causes the bubble to contract and as this happens something very spectacular happens! The bubble starts emitting light. Light, as in photons are being emitted from this bubble of air (now plasma) that is under contraction. I hope that you are as amazed as I was the first time I learned of this effect (that is if you are not already looking for info on SL).

Sonoluminescence Latest Research Results The building block of bubble flows - a single bubble - is an object of fascinating complexity that is studied in another experiment in which single bubbles are acoustically driven. Under certain conditions such a bubble can emit light! This phenomenon is called sonoluminescence. Typical sound energies are in the range of only 10 eV/particle typical light energies are in the range of 1eV/particle. Therefore, we have an energy focusing factor of 10 The immediate questions to ask are: When does this phenomenon occur, i.e., what is the phase space of sonoluminescence? What is the light emitting process? Can one upscale sonoluminescence, i.e., can one push the limits of sonoluminescence towards the region of even more extreme and extravagant states of matter ?

Featured Album: Sonoluminescence by Dan Connor If you like your music predictable, then read no further. Sonoluminescence , the first album by Dan Connor released in 2004, is a tour of the unexpected and will probably not appeal to the linear of spirit. Sonoluminescence leads the listener through an eclectic mix of musical genres – electronica, funk, pop, industrial, and sonic banter that would make Frank Zappa smile. Imagine that someone put music by Beck CellDweller , and the Beatles in a blender long enough to create different chunks, but not long enough to puree. That's the impression. If you enjoy a variety of textures and flavors in the music that you consume, then read on but bring a fork and an appetite. Sonoluminescence opens with Babylon , an ode to creativity and the twists of relationships. It builds on the initial string progression in a classical manner before transitioning to intensive bass dance rhythms. Great line: "It's the reason that all of us dream our dreams, dreaming them, instead of living them." Strong elements of electronica and alternative rock drive the energetic, catchy, and eccentric (true to title) Experimentation . The next track

Milton Comments: 55 pages, 4 ps figures, Invited Lectures at 17th Symposium on Theoretical Physics, Seoul National University, Korea, June 29-July 1, 1998 Report-no: OKHEP-99-01 Zero-point fluctuations in quantum fields give rise to observable forces between material bodies, the so-called Casimir forces. In these lectures I present the theory of the Casimir effect, primarily formulated in terms of Green's functions. There is an intimate relation between the Casimir effect and van der Waals forces. Applications to conductors and dielectric bodies of various shapes will be given for the cases of scalar, electromagnetic, and fermionic fields. The dimensional dependence of the effect will be described. Finally, we ask the question: Is there a connection between the Casimir effect and the phenomenon of sonoluminescence?

We believe that the photo of a single light emitting bubble moving in a torus generated the appearance of a shuttlecock as reported in the thesis of Paul R. Temple U. Vermont 1970 who we credit with the first observation of sonoluminescence from a single bubble. Latest results include the use of a streak camera to observe the emission of an outgoing shock wave from the sonoluminescing bubble. In a 16KHz sound field the strength of the shock wave approaches 1 Million Atmospheres. Two color plates and a black and white show the experiment and data. Physical Review E 2000.

Energies of the present are becoming endangered and may no longer be able to provide us with the one thing we rely on so heavily, electricity. With new and improved technologies, energy production is becoming more efficient and environmentally friendly. The purpose of this site is to present these alternatives to students and teachers, and evaluate them on various criteria. This site has also been developed to allow the audience to take part in the search for the "best" energy source. A forum has been put into place so that students can give their opinions. Also there has been an interactive quiz designed to encourage the learning of these alternatives. "Bad Acid", a cartoon character, has been added to the site to provide interactive and entertaining tours of the web site and its content. These tours equal twenty minutes of animated learning.
