What colors of the visible spectrum are absorbed most?
green and yellow
What colors of the visible spectrum are absorbed least?
orange and red
What colors of the visible spectrum are absorbed only a little(not the most, not the least)?
green

Black
What color has no wavelengths and no light?
Black
What color reflects nothing and absorbs all colors of the visible spectrum?
photosynthesis
Fill in the Blank: Increase of blank corresponds with the wavelengths absorbed.
yellow and green
What two colors are the least important in photosynthesis?
