Abstract For this lab, wave equations were used to predict and experimentally verify the process of producing standing sinusoidal waves on strings of varying masses. After finding different resonance frequencies, these equations were then utilized to ascertain certain characteristics such as the number of nodes, wavelength, frequency and period. Results show a linear wavelength of power dependent mostly on the mass of the string being vibrated. Introduction For this lab the experiment was begun by predicting the mass needed to produce resonance frequencies with the various strings. This was done by first multiplying the wavelength by the frequency, which gives the velocity. To find the force, the velocity was then multiplied by the linear mass density of the string. This figure was then divided by the force of gravity to predict the mass necessary to attach to the string to produce a resonance frequency. The experimental data were copied into Microsoft Excel and the average power was determined
