Query: Experimental methods for the study of standing waves in strings   Several cases of the explanation of the phenomenon of standing waves in
strings, there are few experimental measurement tools when demonstrating this
phenomenon in a classroom, it is for this reason that we have implemented
different forms to show how we can experimentally demonstrate the wave behavior
of string vibration, where variations in the length, frequency and tension of
the string have been made, with the purpose of showing this phenomenon more
generally and clearly for students. In this work, we present the step-by-step
the implementation of two experimental procedures of laboratory concerned with
the study of wave strings, seeking as a primary objective to show students the
experimental way of obtaining and measuring the number of bellies in a string
in addition of being able to calculate both fundamentally and experimentally
the fundamental frequency of each string by varying both its length and its
tension using the resonance frequency. Finally, we present the respective
experimental errors, for each of the assemblies and methods carried out in the
laboratory to perform the measurements shown and registered in this work.
