This is a picture of a bowl of cherries I ate today, which I know reflects light. Why does it not show a complete and clear reflection like a mirror? The answer is because the surface of the cherry skin is rough to waves of light. Rays of light that strike the cherries are reflected in an almost infinite amount of directions allowing us to fully see it. However, the cherries do have a slight reflective glaze on them which means that the surface is probably reflecting some light, and that the surface is not as smooth as a mirror. The basis of sight is the rough surfaces that reflect light off of them in many directions so that our eyes can pick them up.
