I'm trying to find the resonant frequency of glass panes and how the resonant frequency is affected by the thickness of the glass pane. I set up the glass pane with the ends of the glass pane fixed. (I want to pass a first harmonic wave through the glass)
I was thinking that I could tap the glass and hear the frequency the glass rings at (measured using oscilloscope)
Would this be a correct way of measuring the resonant frequency?
(I'm doing this at home, so I understand there is going to be a decent amount of error. I just want find out a relationship between the two variables)
