Instructions
What you see is a transverse wave on a red string being driven by an invisible motor at the left.
You may start and stop the motion as well as single stepping it by using the buttons.
You may also control the Frequency and the Amplitude of the motion by using the sliders.
Play with the simulation and use it to answer the questions provided by the teacher.

This demonstration was created by Andrew Duffy. It was modified by Br.R.W.Harris in order to show only those variables of interest at this point in the course.
