A concave mirror (f = 39 cm) produces an image whose distance from the mirror is one-third the object distance. Determine (a) the object distance and (b) the (positive) image distance.

An object 1.6 cm high is held 3.15 cm from a person’s cornea, and its reflected image is measured to be 0.175 cm high. Part (a)  What is the magnification? Part (b)  What is the image distance in cm? Part (c)  Find the radius of curvature in cm of the convex mirror formed by the cornea.

A concave mirror has a focal length of 39.3 cm. The distance between an object and its image is 66.8 cm. Find (a) the object and (b) image distances, assuming that the object lies beyond the center of curvature and (c) the object and (d) image distances, assuming that the object lies between the focal point and the mirror.

A spherical, concave shaving mirror has a radius of curvature of 0.476 m. What is the magnification of a person's face when it is 0.155 m from the vertex of the mirror (answer sign and magnitude)?
