Waves
Term | Definition |
---|---|
Absorbtion | 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 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 though empty space. |
Frequency | The number of times a wave repeats in a given amount of time. |
Lens | A curved piece of glass or plactic 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 takes up space. |
Mechanical wave | A wave that requires a medium to travel through. |
Medium/Media | A wave that requires a medium to travel through. |
Mirror | A reflecting surface. |
Path | Also known as trajectory; is a path an object follow 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 hoe 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 | 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 travels before it starts to repeat. |
