A 60-year-old man, who has normal vision, has a near point of 93
cm. Instead of using reading glasses, he chooses to use a magnifier
of focal length 15 cm for reading. He reads with his eyes
relaxed.
(a) Find the magnification M.
(b) What is the distance from the page to the magnifier?
(c) What is the maximum angular magnification that can be obtained
with this magnifier by a child with a near point of 14
cm?
