A question about reflection and lenses I was just wondering if anybody could explain to me why I can't see my reflection on a white peice of paper, but I can see an image transmitted onto the paper from a lens.  I'm sure it's a basic answer, but my understanding was that I can't see my reflected image due to the imperfection of the surface of the paper.  Shouldn't that prevent me from seeing an image projected onto the paper as well?
