Textbook Question
Chapter 24, Problem 35P
The lens of the eye. The crystalline lens of the human eye is a double-convex lens made of material having an index of refraction of 1.44 (a though this varies). Its focal length in air is about 8.0 mm, which also varies. We shall assume that the radii of curvature of its two surfaces have the same magnitude. (a) Find the radii of curvature of this lens. (b) If an object 16 cm tall were placed 30.0 cm from the eye lens, where would the lens focus it and how tall would the image be? Is this image real or virtual? Is it upright or inverted? (Note: The results obtained here are not strictly accurate because the lens is embedded in fluids having refractive indices different from that of air.)
