Activity 3

Exploring the displacement bars of the sources

1.    Click on the red box (first box from the left) to show the displacement bar of source S1 . Note that the x and y position of source S1 will be displayed on the right of the checked box. 

2.    Next, click on the green box (just beside the red box) to show the displacement bar of source S2.
3.    Observe the additional new displacement bar on the left side of the simulation. The bar indicates the displacement of the individual waves produced by the individual source S1 and S2. At the bottom of the bar is the value that shows the amplitude of the wave produced by the individual source. You may key in a new value to change the amplitude of the wave.  (Note: Do not shift the position of the source or change the slider position that appears besides the checked box. You can fully explore all the features in this simulation after you have completed this section.)

4.    Select the   play button to start the simulation, paying attention to the two displacement bars.


5.    Reset the simulation by clicking on  reset button.
