waves vocab
| Term | Definition |
|---|---|
| Absorption | the transfer of energy from a wave to medium |
| Amplitude | the distance between the highest crest and the resting position |
| Barrier | something that blocks that way an obstacls |
| bend | to turn or force from straight or even to cued or angular |
| brightness | the lightness of darkness of reflected light (intensity of light ) |
| color filter | a transparent material that absors some color and allows other 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 time 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 | wave that comes from a light source (Ex : visible light - ROYGBIV |
| matter | anything that has mass and take up space |
| mechanical /media | a wave that requires a mudium to travel through |
| medium/media | material through which travel |
| mirror | a reflecting surfuace |
| path | also know as trajectory is the path an object follows in space |
| prism | a piece of glass or transparent material that bends light |
| propagate | the ways wave travels or move |
| proportion | something change 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 happen when it reaches a surface |
| reflection | waves bounding off a medium |
| refraction/refracted | the bending of waves due to change in speed |
| sound waves | a vibration or wave that travel though matter (solid liquid in gas ) and can be heard |
| transmit | to cause ( light heat sound etc) to pass through a medium |
| transparent | allows light to pass through |
| visible light spectrum | the portion of the electromagnetic spectrum that the human eye can view |
| wave | any disturbance that transfers energy from place to place |
| wavelength | the distance the wave travel before it start to repeat |
