waves
Term | Definition |
---|---|
absorption | the transfer of energy from a wave to a medium |
amplitude | the distances between the highest crest and the resting position |
barrier | something that blocks the way; an obstacle |
bend | to turn or force from a 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 ( reflects or emits )n off an object |
color filter | a transparent material that absorbs some colors and allows others to pass though |
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 is 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 light source ( EX : visible light- ROYGBIV |
matter | anything that takes up space |
mechanical wave | a wave that requires a medium to travel through |
medium/media | material through which wave travels |
mirror | a reflecting surface |
path | also know as trajectory ; is the path an object follows in space |
prism | a piece of glass or transport material that bends light |
propagate | the way waves travel or move |
proportion | something changes with regards to something else |
ray | the movement of light from the 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/refraction | the bending of waves due to change and speed |
sound wave | a vibration , or wave that travels through matter ( solid, liquid ,and 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 view |
wave | any disturbance that transfers energy from a place to place |
wavelength | the distance the wave travels before it starts to repeat |
