Objects in mirror are closer than they appear. This a phrase often seen in rear-view mirrors. The mirror's surface is convex, meaning that they give a wider field of view than a flat reflecting surface would give. This optical effect allows a driver to see more of what's behind the vehicle than would otherwise be seen, with the caveat that the things seen appear smaller than they would normally. When the rays from a object hit a convex mirror they reflect off the surface of the mirror. If these reflected rays were to be extended behind the mirror, they would combine at a single point to form an image. This image is formed where the rays emanating from the object appear to intersect behind the mirror. The image you see is formed behind the mirror not in front of it. Convex mirrors form images that are smaller than the object itself. Now, we can say that the image seen in the passenger side rear view mirror is: smaller than it normally would be, is behind the mirror, and that the farther away a object is the smaller it appears to be. Taking all of this into account, one should always head check.
