A piano tuner stretches a steel piano wire with a tension of 800 N. The steel wire is 0.400 m long
and has a mass of 3.00 g. (a) What is the frequency of its fundamental mode of vibration? (b)
What is the number of the highest harmonic that could be heard by a person who is capable of
hearing frequencies up to 10,000Hz?
Identify: The fundamental frequency depends on the wave speed, and that in turn depends on
the tension.
