Mode and open organ pipes

  1. Oct 18, 2011 #1
    1. The problem statement, all variables and given/known data
    Where would you locate a small vent hole to encourage the third mode of an open pipe? The fourth mode?

    2. Relevant equations

    Hint: Where is a node of the desired mode?

    3. The attempt at a solution

    Does this mean 1/3 of the way down for mode 3 and 1/4 of the way down for mode 4?
