Homework Help: Sound Waves in an organ pipe

  1. Apr 18, 2010 #1
    I have to draw frequency on an open and closed pipe. The top horizontal row is open organ pipe and the second horizontal row is a closed pipe. I have draw the frequency of sound on these but the open entrance of the sound is what is confusing me. Are these correct?

    Yup, they are drawn correctly. Note that for the open pipe, the even harmonics also work, it's just for the closed pipe that you only have to consider the odd ones only.
