The crystalline lens of the human eye is a double-convex lens made of material having an index of refraction of 1.46. We shall assume that the radii of curvature of its two surfaces have the same magnitude. Assume the lens is embedded in a fluid having a refractive index similar to air.
If the radii of curvature of this lens are 7.82 mm, what is its focal length?
If an object 10.0 mm tall is placed 17.0 mm from the eye lens, where would the lens focus it?
How tall (in cm) would the image be?
Describe the nature and orientation of the image.
