What are the frequencies of the notes produced in an open and closed p

1.	What are the frequencies of the notes produced in an open and closed pipes in terms of the length of pipe L and velocity of waves v?.
Answer» The frequencies of all the harmonics present in an open pipe are n = (p + 1) \(\frac v{4L}\) = (p + 1) \(\frac v{4(I+2e)'}\) where p = 0,1,2,3,...... The frequencies of the odd harmonics present in a closed pipe are n = (2p + 1) \(\frac v{4L}\) = (p + 1) \(\frac v{4(I+e)'}\) where p = 0,1, 2, 3, … .

Answer»

The frequencies of all the harmonics present in an open pipe are

n = (p + 1) \(\frac v{4L}\) = (p + 1) \(\frac v{4(I+2e)'}\)

where p = 0,1,2,3,......

The frequencies of the odd harmonics present in a closed pipe are

n = (2p + 1) \(\frac v{4L}\) = (p + 1) \(\frac v{4(I+e)'}\)

where p = 0,1, 2, 3, … .
