Question:
As a young P. walkeri matured, the air passages in its crest might increase in length from 1.5 m to 2.7 m, causing a decrease in the standing wave frequencies. Referring to Figure 14-54, do you expect the change in the fundamental frequency to be greater than, less than, or equal to the change in the second harmonic frequency?
