Waves in a String Name Logan Staley Resource: https://phet.colorado.edu/en/simulation/wave-on-a-string In this simulation you can investigate the behavior of waves on a string. Challenge : Determine the speed of the waves at each tension setting (high, medium and low). Settings: Oscillate No end amplitude: 0.8 cm damping: none Explain what measurements you need to make and how you would calculate the speed. Normally you divide the distance by the time to figure out the speed of the wave But can also do wavelength times frequency Explain how to measure the wavelength. To get wavelength you have to divide the wave speed by the frequency Data High Tension Frequency (Hz) Wavelength (cm) Speed 3 2.13 6.4 2 3.2 6.4 1 6.4 6.4 Medium Tension Frequency (Hz) Wavelength (cm) Speed 3 1.2 3.6 2 1.8 3.6 1 3.6 3.6
Low Tension Frequency (Hz) Wavelength (cm) Speed 3 .4 1.2 2 .6 1.2 1 1.2 1.2 Does the speed of the wave depend on the frequency or is it the same for all frequencies? The Speed is constant in there tension groups. Does the speed of the wave depend on the tension? Yes Does the speed of the wave depend on the amplitude? Record your data to prove it. Amplitude is the maximum displacement of particles, with this in mind while looking at the screen shot the left side is Amplitude of .8 while the right side is a Amplitude of 1.25. The right side is bigger due to the amplitude being bigger but the speed doesn’t change,
