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 ( 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 |
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 though 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 |
