1. The problem statement, all variables and given/known data My group and i need to do an experiment for school. We decided to investigate the effect of water level in a vine glass (or volume) on the resonance frequency. Basically does the resonance frequency change when you change add water to the glass. I would just like some help modelling my experiment. We plan on finding the resonance frequency by circling two wet fingers around the rim. We would record this sound and calculate the frequency using a program on a laptop. We repeat with water in the glass. Am i in the right track and what can i do to improve my experiment. 2. Relevant equations 3. The attempt at a solution Basically we haven't done the experiment yet but you can see my attempt/ plan for the experiment under 1.
