Absorption
of certain frequencies of light: one reason for the existence of an
object that is due to the object will be light refraction into the
human eye, and was the result of their feelings, so we can go through
certain method when an object reflects light, making absorption of
certain frequencies, so that only the human eye to reach the white
part, they are superimposed with each other will show a different
color. Paints and dyes is to use this truth to absorb certain
frequencies of light, so that objects in the eyes show different
colors. The reason why there are green leaves are green also due to
leaf chlorophyll to absorb sunlight in the blue and red and other
colors result. Green light is not absorbed.)
