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 other to pass through |
Echo | a repeated sound that is caused by the reflection of a sound wave from a surfaces |
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 com 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 know 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 change with regard to somethings else |
ray | the movement of light from its source to a surface or objects |
ray diagram | shows how light travels including what happens when it reaches a surface |
reflection | waves bouncing off a medium |
reflection /refracted | the bending of waves due to change in speed |
sound waves | 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 disturbance the wave travels before it starts to repeat |
