A flute behaves like a tube open at both ends.If its length is 65.3 cm,and the speed of sound is 340 m/s,what is its fundamental frequency in Hz?
A)130 Hz
B)159 Hz
C)212 Hz
D)260 Hz

Question

Quizplus · Accepted Answer

The fundamental frequency of a tube open at both ends is given by the formula $ f = \frac{v}{2L} $, where $ v $ is the speed of sound and $ L $ is the length of the tube. Substituting the given values, $ f = \frac{340}{2 \times 0.653} \approx 260 $ Hz.
