What Factors Affect the Natural Frequency of a Wineglass?

[06mangro]

Hello,

I was just wondering what the natural frequency (of a wineglass) depends on,


i would say density of the glass, the shape, thickness,

could anyone tell me about in more detail?

Does this apply for any object (as the object gets bigger it becomes more complicated and especially if it has more than one material making it up?)

The length will affect it more than anything; the standing wave that occupies it is determined in large by the length, as this affects the number of nodes that can form..

f=$\frac{nv}{4L}$
n = harmonic [where you can only have odd harmonics [1, 3, 5, etc].]
L = length.
v = velocity of the wave.
