How do objects absorb light?

When the light falls on a certain object, then part of the rays is reflected, and some are absorbed by the atoms of the object's surface, causing a slight heating of it. Light waves of different lengths are different in color, so the color of the surface depends on what waves are absorbed, and which are reflected. For example, you see a green leaf on a tree because it absorbs all colors except green. It is this reflected color you see.
