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
