Ive been given the task of investigating what factors will affect the resonant frequency of a piece of string or wire . I believe it may have something to do with standing or stationary ways. At the moment I believe I have two ways of doing this, one by using string, vibration generator and pulley, the other by using wire, magnet and rheostat.(adsbygoogle = window.adsbygoogle || []).push({});

Both I believe involve the equation fo = ½L x (T/µ).

fo = fundamental frequency

L = length of vibrating wire

T = tension

µ = mass per unit length

Could anyone who has any experience with this formula at all, or knows how to put it into use tell me, particularly the length part, is it node to node or arbitrary lengths. Thanks
