Waves HandsOn need many Device

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

Introduction
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.
