Ametal plate is held fixed in the center and sprinkled with sugar. with a violin bow, the plate is stroked along one edge, and made to vibrate. the sugar begins to collect in certain areas and move away from others. describe these regions in terms of standing waves.

It can be said that the vibration of the sugar particles demonstrates the formation of a region where a maximum amplitude and a minimum amplitude can be observed. It should be noted that at the specific points where the sugar tends to accumulate, these areas have a minimum amplitude, very similar to the nodes, and in the areas where the sugar moves further away, it is a region that has the maximum amplitude, it is very similar to antinodes.
