| Term | Definition |
|---|---|
| Absorption | The transfer of energy from a wave to a medium. |
| Amplitude | the distance |
| barrier | something that blocks the way; an obstacle. |
| bend | to turn or force from straight or even to curved or angular |
| brighness | the lightness or darkness of reflected light (intensity of light) |
| color | what you see when light shines (reflects or emits |
| 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 |
| Electromagnetic wave | a form of energy that can travel through empty spaces |
| Frequency | the number of times a wave repeats in a given amount of time |
| lens | a curved piece |
| light wave | waves that come from a light source Ex: visble light- ROYGBIV |
| matter | anything that has mass and takes up space |
| Mechanical/media | material through which a wave travels |
| mirror | a reflecting surface |
| path | also known as trajectory; is the path an object follows in space |
| prism | a piece of glass or transparent material that bends light |
| propagate | the way waves travel or move |
| ray | the movement of light from its source to a surface or object |
| ray diagram | shows how light travel including what happens when it reaches a surface |
| reflection | waves bouncing off a medium |
| refraction/refracted | the bending of waves due to a change in speed |
| sound wave | a vibration, or a wave, that travels through matter (solid, liquid, or gas) and can be heard |
| transmit | to cause (light,heat |
| transparent | |
| visble light spectrum | |
