SUMMARY
As a wine glass is filled with water, its resonant frequency decreases rather than increases. This phenomenon occurs due to the added mass of the water, which lowers the frequency of the glass's vibrations. The discussion highlights the confusion surrounding the relationship between water level and sound pitch, noting that while splashing sounds may increase in pitch, the fundamental frequency of the glass itself diminishes. The experiment conducted by the user confirms this decrease in resonant frequency as the glass fills.
