The difference between the 2nd overtone of a closed pipe and its 3rd harmonic is 300 Hz. The 3rd harmonic of the closed pipe equals the 4th harmonic of an open pipe. The fundamental frequencies of the closed and open pipes are:

Options:

Answer:

Solution:

2nd overtone = $5 f$ , 3rd harmonic = $3 f$ , so $2 f = 300$ and $f = 150$ Hz. The 3rd harmonic is 450 Hz = $4 f'$ , so $f' = 112.5$ Hz.
