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 (reflected 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 | form of energy that can travel through empty space. |
Frequency | number of times a wave repeats in a given amount of time. |
lens | 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 | wave that requires a medium to travel through. |
Medium/Media | - material through which a wave travels. |
Mirror | reflecting surface |
Path | 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 | the bending of waves due to a change in speed. |
Sound Wave | - a vibration, or wave, that travels through matter (solid, liquid, or gas) and can be heard. |
Transmit | 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 | disturbance that transfers energy from place to place. |
Wavelength | distance the wave travels before it starts to repeat. |
