Question

The fundamental frequency of a pipe that is open at both ends is 564 hz . part a how long is this pipe?

Answer 1

I hope this will be helpful i made a bold assumption of speed of sound since it is not provided

Answer 2

. when a pipe is open at both end
l= k / 2
l= length of the pipe
k=wave length of the pipe
there fore 2l = k
we have
f = v k
f = frequency of the wave
v = velocity of the wave
k = wave length of the pipe
f = v k
f = v (2l)
l = f / 2v
l= 564 / (2 * 344)
l= 564/ 688
l =.82m
l=82m
