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 no ... wledge 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? The buoy will move because the wave will push it. 2. The two images show side views of ocean waves. How are the two sets of waves different? The two images showing the two different sides of the ocean waves are different because the first image of the wave is higher than the second image of the ocean wave. 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? In my opinion, I think that the motion of this transverse wave is moving at right angles. Because, the speed stays the same and the wave power doesn’t change either. 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? I think, that the motion of this longitudinal wave is a wave that is going said to side but in a slow speed. 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.

Select Transverse waves.  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? The motion of the hand is increasing and decreasing. B. Turn off the Lights on checkbox and observe the green dot. What is the motion of the green dot? The motion of the green dot is also decreasing and increasing. C. Follow the motion of a single crest of the wave. How does the crest move? The crest moves to the right because of the hand’s motion. 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. 2. [Show More]
