Standing Waves Experiment Use the Wave on a String Simulation for this lab. 1. 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. 4. For the following trials keep the simulation on Pulse. Pause the simulation immediately after a wave is created to record the data below. Use slow motion to help you capture the wave on the screen. Then let the simulation continue until the wave dissipates. Amplitude Pulse Fixed/Loose Damping Tension Length of Measured (cm) Width End Wave Amplitude (S) (cm) (cm Trial 4 0.75 0.5 Fixed Medium High Trial 5 0.75 0.5 Fixed High High Trial 6 0.75 0.5 Fixed Medium Low Trial 7 0.75 0.5 Fixed High Low . How does increased damping affect waves?6. Can you double the measured amplitude of a wave? Create a simulation that causes two waves travelling along the same side of the string to collide. Record the variables used below to try this, as well as the measured amplitude before the collision and once the two waves converge. Use slow motion It needed to pause the simulations and measure the amplitude. 7. Can you create a point on the string with two waves travelling along it that does not move, or moves only a very little bit, from the reference line? Record the variables used below to try this and discuss what you discovered. 8. Switch to oscillate and experiment with the damping and tension to combine waves.
