Question

A uniform wire of length L, diameter D and density ρ is stretched under a tension T. The correct relation between its fundamental frequency f , the length L and the diameter D is:-

Answer 1

$$\begin{gathered} f=c/\lambda =1/2L*\sqrt{T/\mu } \\ \mu ismassperunitlength=\pi *D^2/4*\rho \\ sofrequency=1/2L*\sqrt{T/\pi *D^2/4*\rho } \end{gathered}$$
