The second harmonic sinusoidal standing wave in a pipe with both ends open has a wavelength of 2.00 m. The sound speed is 340 m/s How many nodes and anti-nodes are there in the displacement wave? How many nodes are there in the pressure wave? Draw the positions of these nodes and anti-nodes. What is the length of the pipe? What is the frequency of the second harmonic? What is the frequency of the fundamental mode in this pipe? If the same pipe was closed at one end and open at the other what would be the frequency of the fundamental mode and the third harmonic?
