Waves
Term | Definition |
---|---|
Absorption | the transfer of energy from a wave to a medium |
Amplitude | the distance from the highest crest to 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 intensity of light |
Color | what you see when light shines reflects or emit off an object |
Color filter | a trans parent 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 waves | a form of energy that can travel through space |
Frequency | the number of times a wave repeats in a giving 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 requires |
Median/media | A material through which a wave travels |
Mirror | Reflecting surface |
Path | Also known as a trajectory is a path the 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 it's source to a surface or object |
Ray diaphragm | Shows how light travels including what happens when it hits a surface |
Reflection | Waves bouncing off an medium |
Refraction/ refracted | The bending of waves due to speed |
Sound wave | A vibration or wave that travels through matter (solid liquid gas)and can be heard |
Transmit | To cause (light heat sound ect) to pass through a medium |
Transparent | Allows light to pass through |
Visible light spectrum | The portion of 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 |
