Question

Lets say you want to make a tube, closed at one end, that has a fundamental frequency of 262 hz. Lets assume that the speed of sound is 343m/s and that the diameter of the tube is 4.0 cm. What length would you cut the tube?

Answer 1

= 0.04 m

We know in closed organ pipe , frequency is given by

For Fundamental frequency, n = 1

putting the values we get

End correction in closed pipe is given as

So the actual length of pipe to be cut
