Assume that a certain concave spherical mirror has a focal length of 12.0 cm.
(a) Locate the image and find the magnification for an object distance of 30.0 cm. (If the image location or magnification is infinite, type INFINITY.)
(b) Do the same for an object distance of 12.0 cm
(c) Do the same for an object distance of 6.00 cm.
