Help me out, about resonance frequency and oscillation....

Factual Questions
1

I have to do a science project. I want it to be on the effects of sound on other objects. I have an experiment where I am going to put a pith ball against a glass and play the frequency that the glass resonates to through my computer. The glass will resonate, making the ball jump and move proving that sound affects objects…

What I need to do is write a paper and I’m having trouble finding information. What should I research? What should I know? Where can I find it? Books, websites, anything. thank you

Well firstly find the resonant frequency of the glass by playing a selection of frequencies and measuring the movement of the ball (and also plot these two values), once you’ve found the resonant frequency of the glass also measure the amplitude at this frequency from the movement of the ball (make sure you also know the amplitude of the sound wave).
