Two open organ pipes, sounding together, produce a beat frequency of 9.0 Hz . The shorter one is 2.50 m long.

The fundamental frequency produced by the E string on a violin is 659.3 Hz. The length of the string is 33.0 cm.  Assuming the speed of sound is 343 m/s, what is the tension on the string if the mass per unit length is 3.47 x 10-4 kg/m?

A guitar string is 104 cm long and has a mass of 3.10 g. From the bridge to the support post (L) is 50 cm, and thestring is under a tension of 540 N. What is the frequency of the first overtone?

A thin 1.0-m metal rod sustains a longitudinal standing wave with vibration antinodes at each end of the rod. There are no other antinodes. The density and Young's modulus of this metal are, respectively, 2900 kg/m3 and 4.5x1010 N/m2. What is the frequency of the rod's vibration?

A string is fixed at both ends and is vibrating at 136 Hz, which is its third harmonic frequency. The linear density of thestring is 5.50 x 10-3 kg/m, and it is under a tension of 2.9 N. Determine the length of the string.

An organ pipe is 120 cm long. What is the second audible harmonic if the pipe is open at both ends? The speed ofsound in air is 335 m/s.

What would be the length (in cm) of a closed - end organ pipe has a 7th harmonic resonance frequency of 1320 Hz? Assume a speed of sound in air of 344 m/s.

Two organ pipes, open at one end but closed at the other, are each 1.14 m long. One is now lengthened by 2.00 cm. Find the beat frequency that they produce when playing together in their fundamentals.

A stretched string fixed at each end has a mass of 40.0g and a length of 8.00m. The tension in the string is 49.0N. (a) Determine the positions of the nodes and antinodes for the third harmonic. (b) What is the vibration frequency for this harmonic?
