An open source physics at Singapore simulation based on codes written by Loo Kang WEE based on ideas from Boon Chien YAP.

Wave is an oscillation accompanied by a transfer of energy that travels through medium (space or mass)
Waves consist of oscillations or vibrations (of a physical quantity), around almost fixed locations.
Concepts illustrated in the simulations include student hands on tool kit to make waves using many devices line up.
There is also a mathematically generated wave to support students' ideas on wave.
My sincere gratitude for the tireless contributions of Francisco Esquembre, Fu-Kwun Hwang, Wolfgang Christian, Félix Jesús Garcia Clemente, Anne Cox, Andrew Duffy, Todd Timberlake and many more in the Open Source Physics community. I have designed much of the above based on their ideas and insights, and I thank the OSP community for which Singapore was honoured with 2015-6 UNESCO King Hamad Bin Isa Al-Khalifa Prize for the Use of ICTs in Education.
