An object is placed 9.10 cm in front of the cornea. (The cornea is thin ans has approximately parallel sides so that the reflection that occurs as light travels from air to cornea to aqueous humor is essentially the same as though the aqueous humor were directly in contact with the air. The aqueous humor has index of refraction n = 1.34 and the radius of curvature of cornea is 7.8 mm.)
(a) What is the image distance for the image formed by the
cornea alone?
(b) The image formed by the cornea serves as an object for the
lens. Treat the lens as a thin lens 6 mm behind the cornea. Find
the optical power of the lens necessary to form an image on the
retina, 21 mm from the center of the lens.

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...
