| Question | Answer |
|---|---|
| absorption | the transfer of energy from a wave to a medium |
| amplitude | the distence between the highties crest and the resting position |
| barrier | something that bloks the way an obstcale. |
| bend | to turn or fource from straight or evan to curved or angular. |
| color | what ypu see when light shineneds off a obdject |
| color filte | a transport materal that absorbs some colors and allows others to pass |
| brite ness | the lightness or darkness of reflection light. |
| echo | a repeted sound that is caused by the reflection of a sound wave from a surfous |
| electromagnetic wave | aform of energy that can travel through empty spaces. |
| frequency | the number of times a wave repets in a given amount of time. |
| lens | a cured peice of glass or plastic desighed to refract light on a spisific way. |
| loight wave | waves come from a light source |
| matter | anything that has mass and takes up space. |
| mechanical wave | a wave that requires a midium to travel through. |
| medium or media | materials through witch a wave travels. |
| mirror | a reflecting surface. |
| 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 way waves travel or move. |
| proportion | something changes with regard to something else. |
| ray | the movment of light frome its source to a surfus or object. |
| ray diagram | shows how light travels , including what happens when it reches a surfus |
| reflection | waves bouncing off a medium. |
| refraction or reflekded | the bending of waves due to a change in speed |
| sound wave | a vibration or wave that travels through matter and can be heard |
| transmit | to cause light heat sound and more to pass through a medium |
| transparent | allows light to pass through |
| visible light spectrume | the portion of the electromagnetic spectrum that the human eye can view |
| wave | any distubance that trancfers energy from place to place |
| wave lenght | the distence the wave travels before it starts to repeat |
