•• (a) An object that is 3.00 cm high is placed 25.0 cm in
front of a thin lens that has a power equal to 10.0 D. Draw a ray di-
agram to find the position and the size of the image and check your
results using the thin-lens equation. (b) Repeat Part (a) if the object
is placed 20.0 cm in front of the lens. (c) Repeat Part (a) for an object
placed 20.0 cm in front of a thin lens that has a power equal to
-10.0 D. SSM

It has become common to replace the cataract-clouded lens of the eye with an internal lens. This intraocular lens can be chosen so that the person has perfect distant vision. Will the person be able to read without glasses? If the person was nearsighted, is the power of the intraocular lens greater or less than the removed lens?•
