Web• A concave mirror caves in on the object; whereas • A convex mirror ﬂexes away from the object. Each mirror has a radius of curvature r (which is inﬁnite for the plane mirror) and a focal length f = 1 2 r. By convention, distances are measured, along the central axis, as positive from the mirror in the direction of the object and 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.
