<p>Wave Lab How do amplitude and frequency affect the velocity of a wave?</p><p>Hypothesis: Hypothesis: As amplitude increases, velocity will ______.</p><p>Hypothesis: As frequency increases, velocity will ______.</p><p>Background:</p><p>Go to https://phet.colorado.edu/sims/html/wave-on-a-string/latest/wave-on-a-string_en.html or phet.colorado.edu and search for “Wave on a String.”</p><p>Play: Try changing different aspects of the simulation.</p><p>Draw a picture of a wave with low amplitude: Draw a picture of a wave with high amplitude:</p><p>Draw a wave with low frequency: Draw a wave with high frequency:</p><p>How does damping affect the wave? How does tension affect the wave?</p><p>Watch just the green dots. How are they moving? Please provide a picture with a few words to explain. Experiment: -Click “oscillate”. -Click “slow motion”. -Choose “none” for damping. -Choose “high” for tension. -Turn on timer. -Place the reference line in place. -Click “no end.” ****You are counting the number of waves that pass through the window. Because each table has 4 waves, it is helpful to just count 4 crests that go through the window. You will have to run the clock to find the time.</p><p>The Effect of Amplitude on Time (and Velocity) Waves Amplitude Wavelength Frequency (Hz) Time (s) (cm) (cm) 4 0.5 2.2 1.5 4 0.5 2.2 1.5 4 0.5 2.2 1.5 Average:</p><p>Waves Amplitude Wavelength Frequency (Hz) Time (s) (cm) (cm) 4 1.25 2.2 1.5 4 1.25 2.2 1.5 4 1.25 2.2 1.5 Average:</p><p>Conclusion: As amplitude increases, velocity ______.</p><p>The Effect of Frequency on Time (and Velocity) Waves Amplitude Wavelength Frequency (Hz) Time (s) (cm) (cm) 4 1.25 2.2 1.5 4 1.25 2.2 1.5 4 1.25 2.2 1.5 Average:</p><p>Waves Amplitude Wavelength Frequency (Hz) Time (s) (cm) (cm) 4 1.25 2.2 3.0 4 1.25 2.2 3.0 4 1.25 2.2 3.0 Average:</p><p>Conclusion: As frequency increases, velocity ______.</p><p>Formula for Velocity of a Wave:</p>
