Suppose a certain musical instrument consists of a pipe which is open at one end and closed at the other. Music is produced as sound waves move through the pipe, creating standing wave patterns. The pipe has a length of 80 cm.
Q1) Find the wavelength of the first, third, and fifth harmonics (show your work).
Q2) Find the frequency of the first, third, and fifth harmonics (show your work).
Q3) Suppose you were riding your bike at 18 m/s towards the instrument as the fifth harmonic was being played. What frequency would you hear?
