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 (reflect 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 which a wave travels through |
mirror | q 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, ect.) 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 from place to place. |
wavelength | the distance the wave travels before it starts to repeat |
