I am once again exploring the use of Geogebra to create simulations for Physics. This is what I managed to put together. It serves to help students visualise how a particle in a transverse wave moves. The slider allows the user to pick any particle along the horizontal direction of the wave.
It has also been optimised for upload as a html5 interactive to be embedded in the Singapore Student Learning Space. Download that version here and import it as a media object in your lesson. All feedback is welcomed.
