5. Analyze: Compare the displacement graph to the tube. What do you notice about the displacement near the center of a compression or a rarefaction? near the center there was slowly movement between... the waves___ 6. Observe: Click Play. How is the progress of the longitudinal waves shown on the displacement graph? ______by going up and down 7. Explore: Click Reset. Experiment with different values for the Strength and Freq. of the tuning fork. A. How does changing the strength of the fork’s vibration affect the characteristics of the longitudinal wave? it change the amplitude of the wave, making it stronger the more it raises B. How does changing the frequency of the fork’s vibration affect the characteristics of the longitudinal wave? it changes the speed of the waves moving and can determine how fast it can go.
