Question
In an open-closed vibrating air column, the ratio of the first two overtones to the fundamental are:
A. 5 and 7 B. 3 and 5 C. 3 and 4 D. 2 and 3
For an open-closed vibrating air column, like a clarinet, only the odd harmonics are present: the overtones have frequencies equal to 3, 5, 7, 9, 11, ... time the fundamental frequency.
For an open tube, which might be a flute, the frequency of each overtone is an integral multiple of the fundamental frequency, such as 2, 3, 4, 5, 6, 7, 8, .....
