William Mauser Webtop I selected the Wave Module for the module that I will review. PHY 518 The wave module is a wave simulation that is similar to a water ripple tank. The images appear three-dimensional. In this module the waves may result from the placement of one or more point sources or a line source. The module will show the resultant disturbance as it occurs across a simulated water surface. The waves can be observed moving or static. The view can be adjusted so that the observer can see the waves from the side or from a top view. The simulation allows observations of supposition with maximum and minimum effects as well as constructive or destructive interference. The module operates like a real ripple tank without any mess or hassle of buying equipment that needs to be set up. It also eliminates the inability of seeing the waves by the students that can occur especially in rooms with poor lighting. The module allows for the removal or addition of wave sources at any location. The observer can make these selections easily. Thus the observer is able to see the effects or accumulation of effects immediately. Position of sources is accomplished with a simple dragging of the cursor or by typing in the coordinates. Other parameters can be altered as well. These include: wavelength, amplitude and phase of the waves. When line waves are used, the angles of the wave can be changed. I feel that this module will be useful as a teaching/demonstration tool. The threedimensional simulations lead to better understanding because students will have something visual to study and discuss. This in itself makes it superior to any techniques or images that I have seen (such as Physlets). B...
