Phys1011: Waves on a String and Frequencies of Tones and VoiceThe purpose of this lab is to examine properties of waves andbecome familiar with terms used in describing waves. Simulatorquestions are adapted from PhET contributors Trish Loeblein andSusie Dykstra. Part 1 – PhET Waves on a String simulator: Watch thelab video. Open Waves on a String(https://phet.colorado.edu/sims/html/wave-on-a-string/latest/wave-on-a-string_en.html).Investigate wave behavior using the simulation for a few minutes.For these lab exercises, set up the sim for a sine wave byselecting “No End” and adjusting “Damping” to “None”. Select‘Oscillate. 2. Write a hypothesis about the relationship between awave variable in the simulator and its effect on wave speed(amplitude, frequency, tension). Test your wave speed hypotheses,and determine the relationships between the wave variables and wavespeed. Make claims about the relationships (direct, inverse, none)between wave variables, using evidence to support claims, andexplaining the relationship between the claim and evidence. 3.Frequency and wavelength are both in your equation for speed. Whyis it that, when you changed the frequency, you did not change thespeed of the wave? 4. The only variable we found that affects thespeed of a wave on a string was the tension of the string. How doesthis relate to how a musician tunes a stringed instrument? 5. Howdoes increasing damping change the wave?
