Confusion about standing waves and harmonics - organ pipes etc.?

  1. ok so i have a major confusion and its really getting to me. So from what i understand of harmonics, the length of the medium is always fixed and only the frequency changes. Is this right? Then why, on organ pipes for example.Assume open open configuration. Say I play a middle tone note C, wouldnt the fundamental frequency length be half the length of the wave. The 2nd harmonic would be 2 times that and the third harmonic would be 3 times the fundamental frequency wave length and so on?

    so why is it changing? shouldn't the length be the same and only the frequency change? im so confused pls help!

    Hi Kratos321! Welcome to PF! :smile:

    It's the same as for a string …

    the length of the medium is the same, but we can fit different numbers of waves into the same length :wink:
