Term | Definition |
---|---|
Absorption | the transfer of energy from a wave to medium |
Amplitude | the distance between the highest crest and the resting position |
Barrier | something that blocks that way an obstacls |
bend | to turn or force from straight or even to cued or angular |
brightness | the lightness of darkness of reflected light (intensity of light ) |
color filter | a transparent material that absors some color 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 empty space |
frequency | the number of time 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 | wave that comes from a light source (Ex : visible light - ROYGBIV |
matter | anything that has mass and take up space |
mechanical /media | a wave that requires a mudium to travel through |
medium/media | material through which travel |
mirror | a reflecting surfuace |
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 ways wave travels or move |
proportion | something change 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 happen when it reaches a surface |
reflection | waves bounding off a medium |
refraction/refracted | the bending of waves due to change in speed |
sound waves | a vibration or wave that travel though matter (solid liquid in 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 travel before it start to repeat |
