A variable length air column (closed on one end) is placed just below a vibrating wire of mass 5.00g, which is fixed at both ends. The length of the air column is gradually increased from zero until the first position of resonance (first harmonic) is observed at 34 cm. The wire is 120 cm long and is vibrating in its third harmonic. If the speed of sound in air is 340 m/s, what is the tension in the wire?
