Example Exercise

Assignment

At what coordinates are hidden sources and what wave length do the waves have?

Note for teacher

In order for this exercise to make sense, you want to hide the sources permanently. Furthermore it is not necessary to add or delete sources from screen. In order to do this and to set up the initial conditions for this exercise, the following JavaScript code is executed upon loading of this web page:

function initialize() {
    simulation.jsSetVisible("no","AddButton");
    simulation.jsSetVisible("no","DeleteButton");
    simulation.jsSetVisible("no","ShowButton");
    simulation.jsAddSource(100, 70);
    simulation.jsAddSource(100, 130);
    simulation.jsStart();
}
