INTRODUCTION TO WAVES This activity uses the Waves Intro and Waves on a String simulation from PhET Interactive Simulations at University of Colorado Boulder, under the CC-BY 4.0 license. https://phet.colorado.edu/sims/html/wave-on-a-string/latest/wave-on-a-string_en.html https://phet.colorado.edu/sims/html/waves-intro/latest/waves-intro_en.html Learning Goals: 1. Make waves with water, sound, and light and see how they are related. 2. Discuss wave properties using common vocabulary. 3. Explain how changing the frequency and amplitude affects the characteristics of the wave. 4. Design an experiment to measure the speed of the wave. WAVES ON A STRING Open Waves on a String , then investigate wave behavior. As you explore, think about how you would describe waves and some reasons the waves might act the way they do. Explain your understanding: 1. Write a list of characteristics to describe the waves. Describe each characteristic in your own words so that any person could understand waves. Use images to help with the descriptions. Tips: Later during this activity, you will relate your own descriptions to scientific ones. It is important that you have your own words to begin your learning, so don’t do any research yet. Also, learning is best when you make your own drawings. Perhaps you can insert images of your own drawings. if not then use images from Waves on a String that look like your drawings. Wave Characteristics: a. b. etc.. 4/16/20 Loeblein https://phet.colorado.edu/en/contributions/view/5466 page 1

Expand your understanding: For steps 2-5 Investigate waves with Oscillate and No End Tips: Helpful tools and 2. Use the Amplitude slider . Answer the questions; include images! a. Define Amplitude in everyday language. b. Explain how the wave behaves as the Amplitude changes using the characteristics you described in #1 3. Use the Frequency slider . Answer the questions; include images. a. Define Frequency in everyday language. b. Explain how the wave behaves as the Frequency changes using the characteristics you described in #1 4. Use the Tension slider . Answer the questions; include images. a. Define Tension in everyday language. b. Explain how the wave behaves as the Tension changes using the characteristics you described in #1 5. Use the Damping slider . Answer the questions; include images. a. Define Damping in everyday language. b. Explain how the wave behaves as the Damping changes using the characteristics you described in #1 4/16/20 Loeblein https://phet.colorado.edu/en/contributions/view/5466 page 2

6. Hold the end of a real rope or the corner of a blanket. Shake to make several waves. a. How can you change the Amplitude of the wave? b. How can you change the Frequency of the wave? c. Did you make waves more like Manual, Oscillate or Pulse? d. Use the simulation to show how your real experiment would look for changing Amplitude . (Explain your experiment and insert images here) e. Use the simulation to show how your real experiment would look for changing Frequency . (Explain your experiment and insert images here) Practice applying your understanding: 7. A wave was generated by Oscillation and paused at two different times. Describe differences and similarities in the characteristics of the wave at different times. 4/16/20 Loeblein https://phet.colorado.edu/en/contributions/view/5466 page 3

Investigate for understanding: 8. Make a wave with the Oscillator with no Damping a. Measure the vertical and horizontal location of a green ball with the ruler and record the time. Use to collect data to make a data table of the time, vertical and horizontal positions of the same green ball. Make sure to include observations when the green ball is above and below the middle line. time vertical (cm) horizontal (cm) b. Make graphs of vertical position versus time and horizontal position versus time . Describe or include images of each graph. c. How do the graphs help you understand the characteristics of waves? d. Predict how the graphs will look if you increase the damping. Test your ideas and explain why damping affects the graphs. 9. Investigate how waves behave with other settings: Fixed , Loose , Manual , Pulse . Write a summary of your observations including images for evidence. 4/16/20 Loeblein https://phet.colorado.edu/en/contributions/view/5466 page 4

Develop your understanding: Explore the Water screen, then explore to make water waves and ways to observe and measure the waves. Explain your understanding: 1. Use your own words and captured images from the simulation to show you can measure: a. Wavelength of longest wave possible b. Wavelength of shortest wave possible c. Height of tallest wave possible 2. Describe your experiments to make waves of different wavelengths and heights including which views and tools were needed and why. Support your explanation with images from the simulation. 3. 4/16/20 Loeblein https://phet.colorado.edu/en/contributions/view/5466 page 5

4. Use your own words and captured images from the simulation to show you can or cannot measure: a. Period of longest wave possible b. Period of shortest wave possible c. Period of tallest wave possible 5. Describe your experiments to measure period including which views and tools were needed and why. Support your explanation with images from the simulation. 6. Use your own words and captured images from the simulation to show you can or cannot measure: a. Speed of longest wave possible b. Speed of shortest wave possible c. Speed of tallest wave possible 7. Describe your experiments to measure speed including which views and tools were needed and why. Support your explanation with images from the simulation. 8. Summarize your understanding of wave characteristics and behaviors by comparing the longest, shortest, and tallest waves. Use these vocabulary words: Frequency, Amplitude, Wave Speed, and Wavelength. 4/16/20 Loeblein https://phet.colorado.edu/en/contributions/view/5466 page 6
