An organ tuner is comparing the fundamental pitch from a certain closed-end organ pipe that is 59.9 cm long
to the sound from an electronic signal generator set to a pitch of 151 hz. the pipe is located in an
environment in which the speed of sound is 346 m/s. how many beats per second will the organ tuner hear?

6.6 beats per second

Explanation:

For a closed-end pipe, the fundamental frequency is given by

where

v is the speed of sound

L is the length of the pipe

Here we have

v = 346 m/s

L = 59.9 cm = 0.599 m

So the fundamental frequency is

The frequency of the signal generator is

So the beat frequency is given by the absolute value of the difference between the two frequencies:

which means that 6.6 beats per second are heard.

vestigial organs (like your appendix) are organs that no longer serve a purpose.
