The speed of a wave travelling on a stretched string of mass per unit length ,u and under tension F is F 'U': . ,u, A thin, 325-cm wire has a mass of 29 g. 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. To what tension must you adjust the screw so that a transverse wave of wavelength 3.5 cm makes 900 vibrations per second? N How fast would this wave travel? m/s Submit
