The diagram below 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 ? λ. 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
Correct Answer: A. proportional to the mass per unit length of the wire
