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 they way;an obstacle |
bend | to turn or force from straight or even to curved |
brightness | the lightness or darkness of reflected light [reflects or emits } off an object |
color fliter | 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 energy that can travel through empty spaces |
frequency | the number of wave repeats in a given amount of time |
lens | a curved piece of glass or plastic designed to refract light |
light wave | waves that come from a light source (Ex; visible light - roygbiv) |
matter | anything that has a mas and takes up space. |
mechanical wave | a wave that requires a medium to travel through |
medium \ media | materials through which a wave travels. |
mirror | a reflecting surface |
path | also known as trajectory ; is the path an object follows in space. |
prisim | a piece of glass or transparent material that bends light |
propagate | the way that waves travel or move |
proportion | something changes with regard to something else |
ray | the movement of light from its source to a source or object |
ray diagram | shows how light travels , including what happens when it reaches a surface |
reflection | waves bouncing off a medium |
refraction | 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 transfer energy from place to place |
wavelength | the distance the wave travels before it starts to repeat |
