Hello, I am trying to create standing waves using this simulation but need to know some information about the string. For instance: What is the mass? Can we determine the tension? firstname.lastname@example.org gabriel schneck 2011.05.06.
Hi, I as well am trying to create a standing wave, however, one end is lose, and one and is fixed. Do you have any tips for me? (email@example.com) Natasha T. 2011.06.16.
The waves are generated on a frictionless surface perpendicular to gravitational force as if they were made by a rope on a table. The simulation is not meant to be highly quantitative. The challenge to make a standing wave is more for making sense of definitions that are in texts and for fun than actually deriving a definition. Trish 2011.06.18.
Natasha, You will need to fix the right end to get a standing wave. Trish 2011.06.18.
Why does the sim break down after observing a standing wave? Jared Rastoka 2014.04.29.
The sim was designed to address many qualitative learning outcomes and is optimized for those. However, some teachers find it useful to approximate standing waves. The sim is based on discrete vector addition and the step intervals are not small enough to enable ideal standing waves. In order to have more small intervals, the processing calculations slow down the sim so much that the sim would not be useful. Trish 2014.05.06.
