A flute behaves like a tube open at both ends.If its length is 70.0 cm,and the speed of sound is 340 m/s,what is its fundamental frequency in Hz?
A) 121 Hz
B) 159 Hz
C) 243 Hz
D) 260 Hz

Quizplus · Accepted Answer

Since the flute is open at both ends, its fundamental frequency can be calculated using the formula f = (v/2L), where f is the frequency, v is the speed of sound, and L is the length of the tube. Substituting the given values, we get f = (340/2*0.70) = 243 Hz. Therefore, the correct answer is C.
