objects don't produce their own light
why do objects appear black in the dark?
200
it contained color
What did the light its self contain?
300
the height of a wave crest or depth of a wave trough,as measured from its rest position
What is amplitude
300
refraction occurs
What occurs when a light wave passes from one material to another?
300
it is the result of all different colors of light mixing.
What is white light such as sunlight?
400
matter in the medium moves back and forth the same direction that the wave travels
What is a compression wave
400
occurs when a light wave bounces off an object
What is a reflection?

500
water waves and seismic waves
What is a combination of transverse and compression waves?
500
This is light
What is a type of wave that travels through empty space and transfers energy from one place to another?
500
the recombined light is no longer white
What happens to the recombined light if one color is removed from the spectrum?
