The equations for each of these can be found above, in our Data - Equations section. Using a frequency generator to drive a normal car speaker, we anchored one end of a 1.85 m, 0.003 kg elastic string to the speaker and the other end to a.550 kg weight. The weight created a tension of 5.39 N in the string, which effectively held the string in place while a frequency was channeled through it. The string was vibrated at certain frequencies, and the distance between the string's nodes was measured. From these measurements, we were able to calculate the wavelengths, pe
