Waves
Term | Definition |
---|---|
Absorption | The transfer of energy from wave to medium . |
Amplitude | The distance between the highest crest and 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 space. |
Electromagnetic Waves | A form of energy that can travel though 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 - ROYBGIV) |
Matter | Anything that has mass or takes up space. |
Mechanical Wave | A wave that requires medium to travel through. |
Medium/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. |
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 Waves | A vibration, or wave, that travels through matter (Solid, Liquid, Gas) ad 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 electromagnetic spectrum that the human eye can be heard. |
Wave | Any disturbance that transfers energy from one place to another. |
Wavelength | The distance the wave travels before it starts to repeat. |
