Waves Gizmo Student Sheet 100% UPDATED 2017-2022

Document Content and Description Below

Student Exploration: Waves Vocabulary: amplitude, crest, frequency, medium, period, power, transverse wave, trough, wave, wavelength, wave speed Prior Knowledge Questions (Do these BEFORE using the ... Gizmo.) 1. 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 Gizmo™, 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? 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 through—in 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. [Show More]
