The principle of mirror imaging
Whether it is mirror or mirror (concave or convex), light will obey Pating and cover mirrors, reflecting light into the eye to form a vision in the retina. In a planar mirror, when a beam of parallel beams touches a mirror, the whole will change forward in parallel mode, when the image is the same as the eye sees.
