Resonance of a Wine Glass

... Resonance of a Wine Glass Final Conclusions Reached The amount of water added to a glass affects its resonant frequency. As more water is added the frequency goes down. This is because the waves lose energy when they drag water molecules along with them around the glass.1 The more water in the glass, the bigger surface area is covered, and more molecules are exposed to the dragging effects of the waves of vibration throughout the glass. All four sets of results taken show a curved trend (although some more prominent than others). Similar shaped glasses appear to produce similar frequencies and my theory is that the energy taken by the water is proportional to the air left in the glass by a factor of k/x2 where could be any constant> 1 and x could be to any power>0. Originally I thought the consistency of the liquid in the glass would affect
