The diagram above shows the wire of a sonometer box set into resonance by a vibrating tuning fork of frequency f, when the wire is stretched by a tension T, the resonating length of the wire is I while the wavelength of the sound produced is \(\lambda\). Which of the following statements about the frequency of vibration of the wire is not correct?
A. proportional to the mass per unit length of the wire B. equal to the frequency of the tuning fork C. inversely proportional to the length of the wire D. proportional to the sqare root of the tension
