If you’ve always wondered how mirrors were made, then check out this interesting “How it’s Made” segment. Video after the jump.
In a plane mirror, a parallel beam of light changes its direction as a whole, while still remaining parallel; the images formed by a plane mirror are virtual images, of the same size as the original object (see mirror image). There are also concave mirrors, where a parallel beam of light becomes a convergent beam, whose rays intersect in the focus of the mirror. Finally, there are convex mirrors, where a parallel beam becomes divergent, with the rays appearing to diverge from a common intersection “behind” the mirror
