Term | Definition |
---|---|
absorption | the transfer of energy form 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 fore form straight or even to curved or angular. |
brightness | the lightness or darkness of reflection 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 form of energy that can travel through 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 refract light in a specific way. |
light wave | waves that come from a light source [ ex: visible light- roygbiv |
matter | anything that has mass and take up space. |
mechanical wave | a wave that requires a medium to travel though |
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 more |
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 bounding 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 | 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 energy from place to place |
wavelength | the distance the wave travels before it starts to repeat |
