Waves
Term | Definition |
---|---|
Absorption | the transfer of energy from a wave to a medium |
Amplitude | the distance between the highest crest and he 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 (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 a surface |
Electromagnetic wave | a from of energy that can travel through empty space |
Frequency | the number of time 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 a takes up space |
Mechanical wave | a wave that 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 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 or moves |
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.) to pass through a medium |
transparent | allow light to pass through |
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 the wave travels before it starts to repeat |
