Is the value of the first peak the resonant frequency then?

I do see part of a sinusoidal waveform. As seen in the last recording in the screenshot. Don't I need to do a spectral analysis or something?

Hi, I did a test, with audacity and a computer oscilloscope and got some nice waveforms, but I am not sure how to analyze these waveforms to determine what the resonant frequency is? I tapped an empty wineglass with a spoon near the microphone and got these:

Hi everyone, I like the idea of using Audacity and the free computer programs, but I am worried that the computer microphone will not be sensitive enough to detect the sound of the wineglass? Would this be a problem?

For a science investigation, I want to investigate how different factors affect the resonant frequency of wineglasses, however, I need some way to measure the frequency quantitatively. Is there some kind of computer program that can do so through the computer microphone? And if so, would the...
