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 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 other s 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 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/media | material threw 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 transparant material that bends light. |
Propagate | the way waves travels 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 of waves due to a change in speed |
Sound wave | a vibration wave that travel through matter (solid liquid 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 |
