The cornea behaves as a thin lens of focal length approximately 1.80cm , although this varies a bit. The material of which it is made has an index of refraction of 1.38, and its front surface is convex, with a radius of curvature of 5.00mm .
(Note: The results obtained here are not strictly accurate, because, on one side, the cornea has a fluid with a refractive index different from that of air.)

A. If this focal length is in air, what is the radius of curvature of the back side of the cornea? - I have this answer - 18.6 mm

B. The closest distance at which a typical person can focus on an object (called the near point) is about 25.0cm , although this varies considerably with age. Where would the cornea focus the image of an 15.0mm -tall object at the near point?

C. What is the height of the image in part B?
Please help with B and C.
