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 straight or even to curved or angular. |
Brightness | The lightness or darkness or 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 through empty space. |
Frequency | The number of times a wave repeats in a given amount of time |
Lends | A curved piece of glass or plastic designed to refract light in a specific way. |
Light Wave | A waves that come from a light source (Ex: visible Light- ROYGBZIV |
Matter | anything that takes up space |
Mechinal 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 be herd |
Wave | Any disturbance that transfers energy from place to place |
Wavelength | The distance the wave travels before it starts to repeat |
