# Wave penetration space

The Wave penetration space has a wave source at one end and a free end at the other (the free end does not interfere with the wave). It can contain one or two blocks. Use it to investigate the effect of passing waves through different types of materials.

Tips for use:

- You can add a second block using the Properties pane.
- To change the material of the block, choose a material from the drop-down list available when you place the cursor over the block.
- To move a block, drag it across the wave space.
