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 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 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 a 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 takes up space. |
mechanical wave | a wave that has requires a medium to travel through. |
medium/media | materiel 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 materiel that blends light. |
propagate | the way waves travel or move. |
proportion | something changes without regard to something else. |
ray | the movement from light from its source to a surface or an object. |
ray diagram | shows how light travels, including what happens when it reaches the surface. |
reflection | waves bouncing of a medium. |
refraction/refracted | the bending of waves due to change and speed. |
sound wave | a vibration,, or wave, that travels through matter ( solid, liquid, or gas) and can be heard. |
transmit | to Couse (light, heat, sound, etc.) |
transparent | allows light to pass through. |
visible light spectrum | the portion of electromagnetic spectrum that a 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. |
