A variable length air column (closed on one end) is placed just below a vibrating wireof mass 5.00g, which is fixed at both ends. The length of the air column is graduallyincreased from zero until the first position of resonance (first harmonic) is observed at 34cm. The wire is 120 cm long and is vibrating in its third harmonic. If the speed of soundin air is 340 m/s, what is the tension in the wire?
A string can have a “free" end if that end is attached to a
ring that can slide without friction on a vertical pole
(Fig. 11-60). Determine the wavelengths of the resonant
vibrations of such a string with one end fixed and the other
free.
