#### How to measure the AC source frequency using sonometer and electromagnet

In this project, I explain how to measure the AC mains frequency using sonometer and electromagnet in the lab. Basically the frequency f of a stretched string depends upon the length of the string l, the tension T, and the mass per unit length m. Defined by relation f=1/2l v(T/m). The wire is made to vibrate by passing AC current of unknown frequency and when frequency of stretched string is in resonance with AC source frequency then the frequency of AC mains n is equal to the frequency f of wire.
