Hi,
I have been conducting a lab experiment using a piece of latex glove to stimulate a tone from a wine glass that is rotating on a turntable. I used the equation [tex]\lambda[/tex]=v/f (using an audio spectrometer setup to find f) to find the wavelength of the emitted tone.
We expected the top part of the glass would be a quarter of the length of the wavelength, as in an organ pipe with one closed end. What I found though, was that it was very close to half.
Does anyone know why my initial assumption was wrong?
Thanks
