Standing waves: Violin String Resonating with concert.

A violin string has a length of 0.350 m and is tuned to concert A, with frequency of A = 440 Hz. Where must the violinist place her finger to play F sharp, with frequency of f sharp = 740 Hz?

If this position is to remain correct to half the width of a finger (that is, to within 0.600 cm), what is the maximum allowable percentage change in the string tension?

Solution Summary

Resonance with a note and allowed change in tension.
