Write at least two hypotheses about the relationships between wave variables in the simulator and their effect on wave speed (e.g. amplitude, frequency, tension).
Added by Craig R.
Step 1
Rationale: Higher tension stretches the medium, reducing its ability to bend, which speeds up wave propagation. Show more…

Describe the relationships between speed, tension, mass, length, frequency, and wavelength for waves on a string. Also describe the relationships between speed, mass density, and Young's Modulus for the speed of sound in a metal tube. 2. Describe how the wavelength will be determined for a wave on a string, knowing the mass, length, and distance between nodes on the string. Also describe how the frequency will be determined and compared to the frequency of the wave driver. 3. Describe how longitudinal vibrations in a rod (inside a tube with cork dust) will be used to calculate the speed of sound in air and how this will be compared to the speed of sound using the temperature.

use the results of experiment 1 to determine the speed of the wave when the rope is set to medium tension. Record here: Analysis: 1) Determine the wavelength that will generate a second harmonic standing wave. Record it here: Use v = λ * f to calculate the frequency of this wave. Record it here: Results of Part 1: Please Note: You can chose to keep all of your measurements in centimeters and velocities in cm/s if you would like – or you can convert them all to meters and m/s, but please try to do one or the other in the tables below so that you can easily see the relationships between the variables. String Length = Tension | Time for pulse to travel 5 round trips | Average Time to travel one round trip | Length of one round trip | Speed of wave = length / time cm/s Low | 60.70 | 12.14 | 15cm | 4.0467 Medium | 20.43 | 4.084 | 15cm | 1.362 High | 12.39 | 2.478 | 15cm | 0.826 Conclusion for Part 1: How does tension affect the speed of a wave in a rope? Experiment Part 2 – Generating Standing Waves of Different Harmonics Set to "Oscillate"; "Fixed End"; Damping = None; Normal; Tension = Medium, Amplitude = 0.20 cm Turn the Ruler and Timer on Use the ruler to measure the length of the piece of string. Record it here: Input this frequency into the simulator and press restart. If the simulation doesn’t look right, double check your calculations.
