Now that we know how to find the focal point of a lens using a distant object, we can see what happens to light rays from objects that are closer … 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
