1. Find a formula for the harmonic frequencies (fn) for a pipe open at only one end based on v=f*lamda and the formula we got for the harmonic wavelengths
2. For a pipe of length 0.40m, find the first five harmonic wavelengths and frequencies.
3. What length pipe is needed to play an A note (440Hz) in the second harmonic?
