A tuning fork is placed next to a 15cm pipe creating the resonant standing wave seen below at two different times. The air inside is at room temperature.
a) Which harmonic is this for the pipe?
b) What is the wavelength of this wave?
c) What is the frequency of the tuning fork?
d) What would be the frequency of the fundamental?
e) What lengths of pipe will resonate with the same tuning fork?
f) If both ends were open, would the pipe still resonate with the same tuning fork? Why or why not?
