A 40-cm-long tube has a 40-cm-long insert that can be pulled in and out. A vibrating tuning fork is held next to the tube. As the insert is slowly pulled out, the sound from the tuning fork creates standing waves in the tube when the total length L is 42.5 cm, 59.4 cm, and 76.2 cm. (Figure 1) Figure 40 cm L 40 cm 1 of 1 What is the frequency of the tuning fork? Assume sound = 343 m/s.

You have an open-open pipe of adjustable length near a taut 60.0 cm, 5.0 gram guitar string which is under a tension of 300 N. You want to adjust the length of the tube so that when it produces a sound in its fundamental frequency, this sound is at the same frequency of the string’s vibration in its second harmonic. What should be the length of the pipe?

A string of mass 9 grams is stretched to a length of 0.4 meters and fastened at both end so that it can freely vibrate. The tension on the string is 2000 Newtons.

A cable with a linear density of u = 0.210 kg/m is hung from telephone poles. The tension in the cable is 550.00 N. The distance between poles is 24 meters. The wind blows across the line, çausing the cable resonate. A standing waves pattern is produced that has 3.0 wavelengthš between the two poles. The air temperature is T'= 24°C. What are the frequency and wavelength of the hum? A =

The G string on a guitar is a 0.46 mm diameter steel string with a linear density of 1.3 g/m. When the string is properly tuned to 196 Hz, the wave speed of the string is 250 m/s. Tuning is done by slowly tightening the string, and stretching it in the process. By how many mm does a 75 cm-long G string stretch when it is first tuned? [Hint: Look up relevant properties of steel as needed.]

A phone cord is 4.89 m long. The cord has a mass of 0.212 kg. A transverse wave pulse is produced by plucking one end of the taut cord. That pulse makes four round trips (down and back) along the cord in 0.666 s. What is the tension in the cord? Hint: Four round trips is a total distance of eight lengths of the cord.
