During our Wave Behavior Lab, we tested several materials for opacity (how much or little light passes through). Recreate your illustration showing the 3 levels of opacity. You may draw on paper and photograph or use the tools here. You do not need to draw 7 pictures, only 3.
As a reminder, the materials used were: 1. Brown Paper Bag, 2. White Square, 3. Clear Square, 4. Rough Square, 5. Brown & Red Square, 6. Black Bookmark & 7. Aluminum Foil.
