I had to come up with a relatively simple physics experiment for an investigation and chose to do a water glass experiment, to make music or at least sound with a wine glass.
I know that when the vibration of the air inside the glass matches the resonant frequency of the glass it produces sound and that adding water changes the resonance of each glass.
We were able to record the maximum dB that each water level sounded and also what we could only assume was the fundamental frequency (using the only available equipment an app for an iPad)
What I'm not sure about is what we can use this information for to help prove the first statement.
Would doing a calculation to find sound level work?
SL =10log I/I0
If it could be used how can we relate the sound level found back to the vibrations of the air and resonant frequency of the glass?
(Hope this is in the right place, It is a homework assignment)
