A sonometer wire of density `rho` and radius r is held between two sharp wedges at a distance L apart. The wire has a tension T. The fundamental frequency of the wire will be
`n = 1/(2L) sqrt((pir^2)/(rho t))`
`n = 1/(2L) sqrt((Trho)/(pi r^2))`
`n = 1/(2l) sqrt((pir^2)/(rho t))`
`n = 1/(2L) sqrt(T/(pi r^2 rho))`
