Document Content and Description Below

Student Exploration: Waves Vocabulary: amplitude, compression, crest, frequency, longitudinal wave, medium, period, power, rarefaction, transverse wave, trough, wave, wavelength, wave speed Prior K ... nowledge Questions (Do these BEFORE using the Gizmo.) 1. A buoy is anchored to the ocean floor. A large wave approaches the buoy. How will the buoy move as the wave goes by? 2. The two images show side views of ocean waves. How are the two sets of waves different? Gizmo Warm-up Ocean swells are an example of waves. In the Waves Gi]mRŒ, you will observe wave motion on a model of a spring. The hand can move the spring up and down or back and forth. To begin, check that the Type of wave is Transverse, Amplitude is 20.0 cm, Frequency is 0.75 Hz, Tension is 3.0 N, and Density is 1.0 kg/m. Click Play ( ). 1. How would you describe the motion of a transverse wave? Click Pause ( ). Notice the crests (high points) and troughs (low points) of the wave. 2. Click Reset ( ). For the Type of wave, choose Longitudinal. Increase the Amplitude to 20.0 cm, and click Play. How would you describe the motion of a longitudinal wave? Click Pause. Notice the compressions in the wave where the coils of the spring model are close together and the rarefactions where the coils are spread apart. Yes itjustdependson thepower One is wide andthe other one is narrowand low the wave is moving in a upand down ratio good wavelength The wave isnt moving up and down but is moving to the right This study source was downloaded by 100000846647825 from CourseHero.com on 11-08-2022 16:06:03 GMT -06:00 https://www.coursehero.com/file/61571437/Gizmo-Wavespdf/ Activity A: Measuring waves Get the Gizmo ready: x Click Reset. Select Transverse waves. x Set Amplitude to 20.0 cm, Frequency to 1.0 Hz, Tension to 2.0 N, and Density to 2.0 kg/m. Question: How do we measure and describe waves? 1. Observe: Click Play. Observe the motions of the hand and of the green dot in the middle. A. What is the motion of the hand? B. Turn off the Lights on checkbox and observe the green dot. What is the motion of the green dot? C. Follow the motion of a single crest of the wave. How does the crest move? In a transverse wave, the motion of the medium (what the wave moves through²in this case, the spring) is perpendicular to the direction of the wave. So, each point of the spring moves up and down as the wave travels from left to right. 2. Measure: With the lights on, click Pause. Turn on Show rulers. A. Use the horizontal ruler to measure the horizontal distance between two crests. What is this distance? This is the wavelength of the wave. B. What is the distance between the two troughs? The wavelength can be found by measuring the distance between two successive crests, two successive troughs, or any two equivalent points on the wave. C. Click Reset. Set the Density to 1.0 kg/m. Click Play, and then Pause. What is the wavelength of this wave? 3. Measure: Click Reset. The amplitude of a transverse wave is the maximum distance a point on the wave is displaced, or moved, from its resting position. Turn off the lights. Click Play, and then click Pause. Use the vertical ruler to measure the height of the green trace, showing how far the green dot moved up and down. A. What is the height of the green trace? B.
