An object 1.50 cm high is held 2.85 cm from a person's cornea, and its reflected image is measured to be 0.170 cm high.
(a) What is the magnification?
multiplied by
(b) Where is the image?
cm (from the corneal "mirror")
(c) Find the radius of curvature of the convex mirror formed by the cornea. (Note that this technique is used by optometrists to measure the curvature of the cornea for contact lens fitting. The instrument used is called a keratometer, or curve measurer.)
