Grass appears green because all of the colors in the rainbow are absorbed into the leaves of the grass except green.

 

Yeah. My physics professor in college tried to get us to believe that was true; that it was every color BUT green, and that is why we could see it.

 

This is why I graduated in English. Don't you think English grammar is much easier to understand than physics?

 

Oh wait. Never mind. :)

Yea...my recollection of my physics classes is that you see the light that is reflected by the object. Green objects reflect only green (or green related wavelengths) and absorbs the others. Black absorbs all wavelengths, white reflects all wavelengths.

 

To elaborate more on this, that same site has more info to go along with the grass is green because of chlorophyll answer:
