how do you find the period of oscillation in physics?
The string is 1.010 m long with tension 4.000 N. The total mass of the string is 14.71 g. Find the period of the oscillation.

the speed of sound on a string is Sqrt[T/u] where T is the tension and u is the mass density; here the mass density is 0.01471 kg/1.010m = 0.01456kg/m, and the speed is 16.57m/s
if this is the speed of sound, we find the frequency from
frequency = speed/wavelength
if we are finding the fundamental mode of oscillation, then the string length is one half the wavelength, so the frequency is
freq = speed/2xLength = 16.57m/s / 2x1.01m = 8.2Hz, and the period is 1/freq = 0.1219 s
