SUMMARY
The natural frequency of an empty wine glass varies significantly between individual glasses, making it impossible to define a "typical" frequency. To successfully break a wine glass using sound waves, one must utilize a signal generator capable of producing sine waves, an amplifier, and a high-quality tweeter loudspeaker. The resonant frequency can be determined by either measuring the sound produced when pinging the glass or comparing it to known musical notes. For optimal results, use lead crystal glasses, which are more effective due to their narrower frequency range and higher amplitude response.
