    the closed pipe [closed at one end] has a constraint at the closed end, which must be a node. the fundamental resonance occurs when \(\lambda = 4L\)

    as \(v = f.\lambda\), then \(\lambda_1 = \frac{v}{f}\) and \(L_1 = \frac{v}{4*f}\)

    look at this: http://hyperphysics.phy-astr.gsu.edu/hbase/waves/clocol.html this site is generally great for illustrations/pictures/diagrams

    so the minimum length in this case would be the length of the fundamental

    yes. get you're head around the science and the formulae you can build .... the locations of the nodes are key.
