3. Gather your data. Use the activity and follow the instructions below to collect your observations. Record them in your data tables. Activity Instructions for Character 1the Observer Select character 1 next to the Go button. This is the observer on the platform. Select the lowest pitch by selecting the bottom music note located to the bottom right of the lab activity. Select the GO button. Record your observations. Select the reset button on the Iab activity. Repeat these steps for the remaining medium and high notes (medium pitch, high pitchy). Activity Instructions for Character 2the Sound Source Select character 2 next to the Sound Waves button. This is the character playing the violin on the train. Select the lowest pitch by selecting the bottom music note. Select the GO button. Record your cbservations. Select the reset button on the Iab activity. Repeat these steps for the remaining medium and high notes (medium pitch, high [#liCeq] ] tiound Waves Investigation Worksheet MName Part 1 Pre-lab Questions 1. For a wave, describe the relationship between frequency and wavelength. 2. List the following mediums in order from fastest to slowest in terms of sound wave speed. Air (20C), Water (20C), Glass, Water (0C), Seawater (20C) 3. Explain why the speed of sound is different in air compared to water. 4. Answer the following questions in terms of a wave's frequency, wavelength, amplitude, and energy. * Describe the characteristics of a high pitch wave. * Describe the characteristics of a high-volume wave. Part 2 Doppler Effect Investigation 1. Generate your prediction and record your hypothesis: If the sound source is moving . then a stationary observer will hear pitch. 2. Collected Data Data Table Character 1, the observer Selected Pitch Pitch Observations away from the observer High note Data Table Character 2, the sound source Selected Pitch Pitch Observations away from the observer High note Part 3 Data Analysis and Conclusions 1. For the observer, what happened to the sound wave's pitch as the sound source moved away from it? 2. For the person playing the violin {the sound source), what happened to the sound wave's pitch as it moved away from the ocbserver? 3. Why did the observer [Character 1) hear a different sound than the violin player? Use your knowledge of sound waves and evidence from this investigation to support your response. 4. Describe two ways that your understanding of the Doppler effect could be applied to your everyday life
