Chapter 2: Q19E (page 498)
A thin, 75.0cm wire has a mass of 16.5g. One end is tied to a nail, and the other end is attached to a screw that can be adjusted to vary the tension in the wire. (a) To what tension (in newtons) must you adjust the screw so that a transverse wave of wavelength 3.33 cm makes 625 vibrations per second? (b) How fast would this wave travel?
Short Answer
Hence, the tension in the screw must be adjusted to 9.53N so that transverse wave of wavelength 3.33 cm makes 625 vibrations per second. This wave will travel at a speed of 20.8m/s.
