Additional Learning Tools and Resources
Watching a presentation is a passive activity. Getting information is important ... but its not the destination or end point. Now that you've watched the video, its time to do something with the information you've heard. It's time to act on it. The resources below provide an opportunity to do this. We encourage learners to solidify their learning through the use of one or more of the following resources.
Physics Interactives: Standing Wave Maker
Our interactive simulations allow you to playfully alter a variable and observe the result in the form of an animation. Ask a question and pursue the answer. This one challenges you to find "just the right frequency" to cause a rope to vibrate as a standing wave. Great tool! And follow it up with the Concept Checker (below).
Concept Checkers, Standing Waves
A Concept Checker provides a student with a quick assessment of understanding associated with a resource on our website. This one is intended to accompany the Standing Wave Maker simulation (above). Download
the student activity sheet that goes with the simulation; work through the activity and then do the Concept Checker. It's a great way to further your learning.
Minds On Physics, Wave Motion Module, Mission WM7
This mission from our Minds On Physics program may be our most effective follow-up to the video. Give yourself the challenge and rise to the occassion. You got this!
Concept Builders, Waves and Sound Chapter: Name That Harmonic (Strings)
This Concept Builder is also a great fit to the video. You will be challenged to detemine the harmonic number based on a standing wave pattern, relate the frequency of one harmonic to that of another, and determine the wavelength of a wave from the pattern and the length of the string (or rope).
Physics Classroom Tutorial, Vibrations and Waves Chapter, Lesson 4 - Nodes and Antinodes
When you need to quickly review, brush up, and revisit the ideas in the video, turn to the Physics Classroom Tutorial page that accompanies the video. This page discusses how to recognize a harmonic number from the pattern of nodes and antinodes in a standing wave diagram.
Physics Classroom Tutorial, Vibrations and Waves Chapter, Lesson 4 - Standing Waves and Harmonics
This Tutorial pages discusses the standing wave diagrams and the mathematical relationships for the various harmonics of a vibrating rope (or string or wire).
