Comparison of reflections of a pen in an ordinary mirror (left) and two perpendicular mirrors forming the first type of non-reversing mirror (right). The latter also illustrates the visible line in the middle if measures are not taken to minimise it. A non-reversing mirror can be made by connecting two regular mirrors at their edges at a 90 ...
