| amplitude | the distance between the highest crest and the resting position. |
| barrier | something that blocks the way,an obstacle. |
| bend | to turn or force from straight or even to curved or angular. |
| brightness | the lightness or darkness of reflected light. |
| color | what you see when light shines off an object. |
| color filter | a transparent material that absorbs some colors and allows others to pass through. |
| echo | a repeated sound that is caused by the reflection of sound wave from a surface. |
| electromagnetic wave | a form of energy that can travel through empty space. |
