Question

The tension in piano wire is 10 N.What should be the tension in the wire to produce a note of double the frequency?

Answer 1

Answer:

The tension in piano wire is 10 N. The tension in the wire should be 40 N to produce a note of double the frequency. Velocity of the traveling wave in the stretched string can be determined by tension and the mass per 1 length of that string. For any string of particular length is measured in cm. For such kind of string, the unit of the fundamental frequency is Hz.
