The purpose of this experiment was to observe single bubble sonoluminescence. Sonoluminescence is the conversion of sound waves into light and requires resonating a circuit with a flask filled with degassed water. The resonating flask should allow a bubble to balance in the centre of the flask, and in the right conditions should exhibit sonoluminescence and emit light. I used a resonating RLC circuit with piezoelectric transducers acting as capacitors. Whilst I ensured both the circuit and flask were at resonance, I did not observe sonoluminescence. This could be attributed to the low voltage produced by the circuit, or the instability of the function generator.
