Question

An engineer measures the frequencies of the audible standing waves in an organ pipe. He finds two adjacent tones at 420 and 540 Hz.

(a)

On the basis of this discovery, the engineer computes the pipe's fundamental frequency. What is its value (in Hz)?

Hz

(b)

Is the pipe open at both ends or only one?

open at both ends

open at only one end

(c)

The air within the pipe has a temperature of 20°C and is at atmospheric pressure. How long (in m) is the pipe?

m

While exploring an abandoned cathedral, you find an old pipe organ. Only one pipe still works, but most of the pipe's harmonic frequencies are absorbed before you can hear them due to overgrowth and debris. The harmonic frequencies you hear are 138 Hz , 230 Hz , and 322 Hz . a. Is the pipe closed on one end or is it open on both ends? Closed on one end. Open on both ends. This choice is not correct. b....
