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 |
brightnesss | 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 surface |
electromagnetic wave | a form of energy that can travel through empty space |
freqency | 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 waves | waves that comes from a light source (EX visible light-ROYGBIV |
matter | anything that has mass and takes up space |
mechanical wave | a wave the 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) |
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 place to place |
wavelength | the distance the wave travel before it starts to repeat |
