Waves
| Term | Definition |
|---|---|
| absorption | the transfer of energy from a wave to a medium. |
| 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 (intensity of light). |
| color | what you see when light shines (reflects or emits) 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 a sound wave from a surface. |
| electromagnetic wave | a form of energy that can travel through empty space. |
| frequency | the number of times a wave repeats in a given amount of time. |
| lens | a curved piece of glass or plastic designed to refract light in a specific way. |
| light wave | waves that come from a light source (Ex: visible light-ROYGBIV). |
| matter | anything that has mass and takes up space. |
| mechanical wave HI | a wave that requires a medium to travel through. |
| medium/matter | 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. |
| proportion | something changes with regard to something else. |
| ray | the movement of light from its source to a surface or object. |
| ray diagram | shows how light travels including what happens when it reaches a surface. |
| reflection | waves bouncing off a medium. |
| refraction/refracted | bending of waves due to change in speed |
| sound wave | vibration or wave that travels through matter(solid, liquid, gas) and can be heard |
| transmit | to cause(light, heat, sound) to pass through a medium |
| transparent | allows light to pass through |
| visible light spectrum | portion of electromagnetic spectrum that the human eye can view |
| wave | any disturbance that transfers energy from place to place |
| wavelength | the distance the wave travels before it starts to repeat. |
