A typical human lens has an index of refraction of 1.430. The lens has a double convex shape, but its curvature can be varied by the ciliary muscles acting around its rim. At minimum power, the radius of the front of the lens is 10.0 mm, whereas that of the back is 6.00 mm. At maximum power, the radii are 6.50mm and 5.5mm, respectively. If the lens were in air:
What would be the maximum power and associated focal length of the lens?
What would be the minimum power and associated focal length of the lens?
At maximum power, how far behind the lens would the lens form an image of an object 11.5 cm in front of the front surface of the lens? (Image distance behind the lens)

The crystalline lens of the human eye is a double-convex lens made of material having an index of refraction of 1.44 (although this varies). Its focal length in air is about 8.00 mm , which also varies. We shall assume that the radii of curvature of its two surfaces have the same magnitude. (Note: The results obtained in the parts A, B and C are not strictly accurate, because the lens is embedded in fluids having refractive indexes different from...

An object placed 20 cm in front of a lens results in an image being formed 24 cm behind the lens. Each surface of the lens is convex (bulging away from the optical plane) with the same radius of curvature, and the index of refraction of the glass composing the lens is Tiens =1.4. What is the radius of curvature of either side of this lens (to the nearest tenth of a cm)? Note, once again, the focal length of...
