I am a high school student that has attempted to carry out the experiment for the Doppler effect using an RC car going at constant speed, a sound source at constant frequency and phyphox app to measure the change in frequency. Unfortunately my experiment didn’t work as planned due to the noise from the RC car and so my data wasn’t good to be analyzed. What I’m trying to do with this data is to analyze rate of change, maxima, minima and really understanding properties of graphs and maybe coming up with a general formula for the graph at certain intervals. I am proposing you if you can please aid me with already measured data of frequency shift so I can use in my analysis.
Thanks to everyone for your help.
