Avariable-length air column is placed just below a vibrating wire that is fixed at both ends. the length of the air column, open at one end, is gradually increased from zero until the first position of resonance is observed at =34.2 cm. the wire is 129 cm long and is vibrating in its third harmonic. if the speed of sound in air is 340 m/s, what is the speed of transverse waves in the wire? assume that the displacement antinode in the air column is exactly at the open end.
