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 from straight or even curved or angular. |
Brightness | the lightness or darkness of reflected light |
color | what you see when light shines off an object |
color filter | a transparent material that absorbs some colors and allows others to pass |
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 repeats in a given part 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 |
matter | anything that has mass and takes up space |
mechanical wave | a wave that requires a medium to travel through |
medium | material through which waves travel through |
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 when 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 an medium |
refraction | the bending of the wave due to the change in speed |
sound wave | a vibration,or wave, that travels through matter and can be heard |
transmit | to cause , 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 |
