Physics Name _________________________ PhET - Waves on a String Date __________________________ 1. Open the Waves on a String Simulation from PhET. 2. Set the damping to zero. 3. Change the setting to “oscillate” rather than manual. Choose “no end” rather than fixed end. Set tension to high. Check the “ruler” and “timer” boxes. a. Do not change the amplitude or tension settings during this experiment. b. Leave the damping setting at zero. c. Use the ruler to measure the wavelength (in meters!) of your wave. To accomplish this, it works best if you pause the wave motion to get your measurement. Drag the ruler to move. d. For five different frequencies, measure the wavelength of the wave produced. Record the frequencies and wavelengths in a table below: Tension setting = ________ Amplitude setting = ________ Trial Frequency (Hz) Wavelength (m) Wave Speed (m/s) 1 2 3 4 5 e. Using logger pro, create a graph of wavelength vs. frequency. * Draw a sketch of the resulting graph that includes all necessary components. * Write the general equation for the line. * Write the translated equation for the line. * What is the relationship between frequency and wavelength? (write a sentence) * If you double the independent variable, what happens (be specific) to the dependent variable? f.
