Understand the lens of the eye. The crystalline lens of the human eye may be modeled optically as a converging lens with an index of refraction of 1. 44 and a focal length in air of about 8. 00 mm. (Note: because the focal length of the lens varies, and is embedded in fluids having refractive indexes different from that of air, such a model is at best approximate)
(a) If an object 14. 0 cm tall is placed 28. 0 cm from the eye lens, where would the lens focus it?
(b) How tall would the image be?
(c) Is the image real or virtual? Is it inverted or upright?
