Standing Waves Experiment Use the Wave on a String Simulation for this lab. 1. Open https://phet.colorado.edu/sims/html/wave-on-a-string/latest/wave-on-a-string_en.html. For this first simulation, click Pulse on the top left, and the rulers and timer on the bottom right. Adjust the settings as given below to find the length and measured amplitude of the wave, as well as the time to dissipation. Record observations about the wave in the following questions. Be sure to stop the simulation between changes to the variables to get a uniform wave. Amplitude Pulse Fixed/Loose Damping Tension Length of Measured (cm) Width End Wave Amplitude (s) (cm) (cm) Trial 1 0.75 0.5 Fixed None High Trial 2 0.75 0.5 Loose None High Trial 3 0.75 0.5 Fixed None Low 2. How did the wave change between Trial 1 and Trial 2 when the simulation switched from a fixed end to a loose end? 3. Describe how the wave changed when the tension went from high to low for the fixed end string
