Waves GIZMOS Lab Sheet/ Student Exploration: Waves

This GIZMOS Lab should be done Wednesday (11/4) and Thursday (11/5) to stay current with your Weekly Learning Plan. Student Exploration: Waves Directions: Follow the instructions to go through the simulation. Respond to the questions and prompts in the orange boxes. Vocabulary: amplitude, compression, crest, frequency, linear mass density, longitudinal wave, medium, period, power, rarefaction, transverse wave, trough, wave, wavelength, wave speed Prior Knowledge Questions (Answer 1&2 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 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. (Note: In this Gizmo, “density” refers to the linear mass density, or mass per unit length. It is measured in units of kilograms per meter.) 1. Click Play ( ) in the GIZMO. 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 ( ). Choose the Longitudinal wave and increase the Amplitude to 20.0 cm. Click Play. How would you describe the motion of a longitudinal wave? Click Pause. Notice the com
