I understand how a magnifying glass works as a convex lens, however I am curious as to how one can explain using it as a mirror.
When I observe the reflections off of a magnifying glass, strangely enough it seems to create two reflections: one that is inverted and one that is upright. How is this so? Shouldn't a magnifying glass simply act as a convex mirror, just as it acts as a convex lens? Which images are real, and which ones are virtual images?
I've attached an image I took as an example. In the image, the same house is reflected twice--one is inverted, one is upright.
