Check the Rulers box (equation) that relates wave speed and frequency Sketch your graph and its fit Based on the answers above, why do you think tension does NOT appear in the and the Timer box. Choose No End. equation. universal wave equation? a. Do not change the amplitude or tension settings during this experiment. b. Use the ruler to measure the wavelength of your wave (the distance from crest to crest). c. Leave the damping setting at zero. d. For five different frequencies, measure the wavelength of the wave produced. Record the frequencies and wavelengths in a table below: Repeat this experiment for a different amplitude and the same tension used previously Summarize your results.
