Consider a pipe of length L that is open at one end and closed at the other end. What are the wavelengths of the three lowest-pitch tones produced by this pipe?
A) 2L, L, L/2
B) 4L, 2L, L
C) 2L, L, 2 L/3
D) 4L, 4L/3, 4L/5

For a pipe open at one end and closed at the other, the wavelengths of the harmonics are given by 4L/n, where n is an odd integer (1, 3, 5,...). Thus, the wavelengths of the three lowest-pitch tones are 4L (n=1), 4L/3 (n=3), and 4L/5 (n=5).
