1. The problem statement, all variables and given/known data Diverging lenses produce a "virtual" image, which can be seen but can't be projected, and converging lenses produce a "real" image which can be projected but not seen. How come we can see the image produced by a converging lens, which is supposed to be a real image? 2. Relevant equations None, I don't think I'll need to use any equation for this. 3. The attempt at a solution I'm clueless... why is it that real images can in theory not be seen? I know that when I look through a magnifying glass, which is a converging lens, I can definitely see something. Is it because the image is "projected" in my retina? If I trace the rays of light through the lens I get something like this: http://upload.wikimedia.org/wikipedia/commons/6/69/Converging_lens_object_far.png meaning the image is inverted and shrunken, but I can't get any further than that. Thanks in advance!
