Waves
Term | Definition |
---|---|
absorbtion | 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 obsticle |
bend | to turn or force from straight or even to curved or angular |
brighteness | the lightness or darknessof reflected light |
color | what you see when light shines off an object |
color filter | a transparent miteral that absorbs some colors and allows other t pass through |
echo | a reapeted sond that is caused by the reflection of a sound wave from surface |
electromatic wave | a form energy that can travel through empty space |
frequncy | the number of times a wave repeats in a given amount of time |
lens | a curved peice of glass or plastic desighned to a refract light in a specific way |
light wave | waves that come from a light source |
matter | anything that has mass and takes up space |
mechanical wave | a wave that requires a medium to travel through |
mirror | a refelcting surface |
path | also known as trajectory |
prism | a peice a of glass or transparent material that bends light |
propagate | the way the waves travel or move |
proportion | something changes with regard to something else |
ray | the movement of light from its source to a surface 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 |
transmit | to cause to pass through a medium |
transparent | allows light to pass through |
visible light spectrum | the portio of the electromatc spectrum that the human eye can view |
wave | any disturbance that transfers energy from place to place |
wavelength | the distance the wavetravels before it starts to repeat |
