waves
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 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 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 waves | 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 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 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, 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 | - to cause (light, heat, sound, etc.) to pass through a medium. |
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. |
