Best ResponseYou've already chosen the best response.1go back to basics and draw the wave shapes starting from the given that v = const and v = \(f.\lambda\) we get v = \(f_n.\lambda_n\) and, for the harmonics for an open air column: \(L = \lambda_1/2 = 2\lambda_2/2=3\lambda_3/2 = 4\lambda_4/2 = \ ...n\lambda_n/2\) for the 3rd harmonic, \(f_3 = v / \lambda_3 = \frac { v }{\frac{2L}{3}} = \frac{3v}{2L}\) \(f_3 = \frac{3*346}{2*0.54} = 961Hz\)

Best ResponseYou've already chosen the best response.1harmonics for open ended go in halves: http://hyperphysics.phyastr.gsu.edu/hbase/waves/opecol.html#c3 everything else follows from that
