We walked into class, just like every single day. we got into groups of three to perform a lab, which was to create different kinds of waves and time their speeds. We had to compare "pluck" waves and standing waves. The goal was to figure out whether the different waves would give us the same results and whether the frequency 0f the standing wave affect our speed measurement. The types of waves were first harmonic, second harmonic, third harmonic, and fourth harmonic. We also did the pluck waves. We had a designated timer, holder, and wave maker during the lab. We used a giant metal slinky to perform our experiments. At the end of our lab, we figured out that the results were very similar but the frequencies were a bit different. The frequency of the pluck wave was not as fast as the frequency of the standing waves.
