Waves
Term | Definition |
---|---|
Absorption | the transfer of energy from a wave to a medium |
Amplitude | the distance between the highest crest and a resting position |
Barrier | something that blocks the way: an obstacle |
Bend | to turn or force from straight or even curved or angular |
Brightness | the lightness or darkness of reflected light (intensity of light) |
color | what you see when a light shines (reflects or emits) off an object |
color filter | a transparent material that absorbs some colors and allows others to pass trough |
echo | a repeated sound that is caused by reflection of a sound wave from a surface |
electromagnetic wave | a form of energy trough an 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 reflect 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 trough which a light travels |
Mirror | a reflecting surface |
path | also known as trajectory: is a 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 in 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 trough |
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 waves travels before it starts to repeat |
