Sign orientation in mirrors and lenses

WebConcave mirrors, on the other hand, can have real images. If the object is further away from the mirror than the focal point, the image will be upside-down and real---meaning that the image appears on the same side of the mirror as the object. The closer the object comes to the focal point (without passing it), the bigger the image will be. WebNo image is formed. Light rays from the same point on the object will reflect of the mirror and neither converge nor diverge. After reflecting, the light rays are travelling parallel to each other and do not result in the formation of an image.

WebThe three types of images formed by mirrors (cases 1, 2, and 3) are exactly analogous to those formed by lenses, as summarized in the table at the end of Image Formation by Lenses. It is easiest to concentrate on only three types of images—then remember that concave mirrors act like convex lenses, whereas convex mirrors act like concave lenses.
