# Sources

Three types of waves sources can be added to 2D wavespaces:

- Point sources
- Line sources
- Moving point sources.

They will begin generating waves as soon as they are added to the wavespace.

Tips for use:

- To give velocity to a moving point source, move your cursor over the moving point source and drag on the velocity handle shown. Next, use the vector displayed to choose the source's initial velocity and the direction in which it will travel. The source will start to move as soon as you release the mouse button.
- You can add a graphic to a wave source using its Properties pane.
