| Sonoluminescence is the process of turning sound energy into light. Two parameters, florescent dye and resonator wall thickness, are studied to determine how the visible light output of multi-bubble sonoluminescence is affected by each. The visible light output from a control setup is compared subjectively to the visible light output from setups testing each of the experimental parameters. A photomultiplier tube detector was unavailable for use in this study. The control setup is comprised of a traditional Pyrex spherical flask filled with degassed water and an ordinary air bubble. Since a large part of the light emitted in sonoluminescence is in the ultraviolet region of the spectrum, a second setup, the same as the control setup, is used with the exception that a fluorescent dye is dissolved in the water. The setup for the thinner-walled resonator is the same as the control with the exception of the thinner wall thickness and slightly different resonator volumes. By eyesight alone, both parameters appeared to increase the visible light output of multi-bubble sonoluminescence at similar experimental conditions. Further studies should be pursued to qualitatively determine how each parameter affects the visible light output of multi-bubble sonoluminescence. |
