What are the factors that affext the fundamental frequency of a wine glass?

In a wine glass, how would the length of the water in the glass (height) affect the fundamental frequency. Also would the thickness on the glass rim affect the fundamental  frequency also.

The fundamental frequency of a wine glass is dominated by standing waves in the cylindrical part of the wall.  The bell of the glass flexes in and out, kind of like its being squeezed and unsqueezed repeatedly.  Adding water causes the vibration to be stopped below the water level, so the cylinder becomes shorter relative to its width, which raises the frequency.  Thickening the walls does the same.

If you cut out any section of the glass in the bell as viewed from the side, it will look like a vertical sliver.  It vibrates kind of like a ruler or a door stop.  Making the sliver shorter or wider will make it less flexible, so it will vibrate faster.

I hope this isn't a homework problem.
