Learning Exercise


Material: Stringwave
Submitted by: Susan Phillips on May 02, 2010
Date Last Modified: May 02, 2010
Title: Stringwave lab
Description: Lots can be done with Stringwave, but I have limited the concepts to be demonstrated to two as part of a larger lab.
Type of Task: Individual, Student-centered, Unsupervised
Topics: Amplitude, tension, frequency, damping, standing waves, reflection
Audience: College General Ed, College Lower Division, College Upper Division, High School
Prerequisites Skills: screen capture
Learning Objectives: Students will: 1. adjust the tension, damping,amplitude and frequency of a virtual string to create reflection. 2. adjust the tension, dampling, amplitude and frequency of a virtual string to create standing waves.
Text of Learning Exercise: Stringwave demonstration of wave properties Using the Stringwave program, demonstrate the following concepts: Standing waves and Reflection. List the concept, how you had to set up the program (manual/oscillate/pulse, fixed end/loose end/no end, level of damping). Tell what happens in each case. Capture and paste one figure for Standing waves and two for damping to compare high and low damping. Standing wave Type of wave setting = Amplitude = Frequency = Damping = Tension = Reflection: Type of wave setting = Damping = 0 Tension =
