Waves
Term | Definition |
---|---|
Absorption | The transfer of energy from a wave to a medium. |
Amplitude | The distance between the highest crest and the resting point. |
Barrier | Something that blocks the way ; an obstacle. |
Bend | To turn or force from straight or even curved or angular. |
Brightness | The lightness or darkness of reflected light {reflects 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 waves | a form of energy that can travel through 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 - ROYGBIV) |
Matter | anything that has mass and takes up space. |
Mechanical wave | a wave that requires a 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 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. |
