QUESTION:

(II) (a) At \(T=20^{\circ} \mathrm{C}\), how long must an open organ pipe be to have a fundamental frequency of \(294 \mathrm{~Hz}\) ?

(b) If this pipe is filled with helium, what is its fundamental frequency?

ANSWER:

Step 1 of 3

Whenever a sound wave of specific frequency moves through different types of tubes (different end conditions of the tube), then the wavelength of the tube varies with the end conditions. The relation between the tube’s wavelength and its length is linear.
