A closed organ pipe of length 0.750 m is played when the speed of sound in air is 340. m/s. What is the fundamental frequency?
A) 171. Hz
B) 570. Hz
C) 0.113 kHz
D) 0.228 kHz
E) 57.0 Hz

Question

Quizplus · Accepted Answer

The fundamental frequency of a closed organ pipe is given by:f = (v/4L)where v is the speed of sound and L is the length of the pipe.Plugging in the given values, we get:f = (340 m/s)/(4 * 0.750 m) = 113.33 HzConverting to kHz, we get:f = 113.33 Hz / 1000 = 0.113 kHzTherefore, the correct answer is C.
