Waves
Term | Definition |
---|---|
Absorption | the transfer of energy from a wave to a medium |
Ampitude | the distance between the highest crest and the resting point |
Barrier | Something that blocks the way; the 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 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 to pass through |
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 of 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 a 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 and 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 |
