This simulator demonstrates the driven oscillation of a single gas bubble trapped at a pressure antinode of a standing acoustic wave, showing how the bubble radius cycles through slow expansion and rapid, violent collapse, and how a brief light flash is produced near the point of minimum radius on each acoustic cycle.
Adjust the driving sound frequency and acoustic pressure amplitude to see how the bubble's growth-and-collapse cycle changes, watch the radius-versus-time curve to see the fast collapse phase, and observe how the timing, brightness, and duration of the simulated light flash respond to your settings.
Controls include driving frequency, acoustic pressure amplitude, ambient liquid pressure, and bubble equilibrium radius, which together determine the shape of the bubble's oscillation cycle and the intensity and timing of the simulated light flash.
In real single-bubble sonoluminescence experiments, the flash timing can stay synchronized with the driving sound wave to within tens of picoseconds, cycle after cycle, for millions of cycles in a row, an astonishing degree of reproducibility for such a violent, fast event.
