A 58.6cm long wire with a mass of 4.21g and a tension of 828.0N passes across the open end of an open-closed tube of air. The wire, which is fixed at both ends, is bowed at the center so as to vibrate at its fundamental frequency and generate a sound wave. Then the tube length is adjusted until the fundamental frequency of the tube is heard. What is the length of the tube? (Assume v_sound = 340.0m/s)
