1 A Jeweler Has A Near Point Of 30cm But Wants To See A Diamond Closer Up At A Distance Of 8cm From Her Eye So S 1 (47.01 KiB) Viewed 42 times

A jeweler has a near point of 30cm, but wants to see a diamond
closer up -- at a distance of 8cm from her eye -- so she puts on a
special pair of glasses with a strong lens over one eye. This lens
has a focal length of F. A) When she uses this lens, the diamond
appears X times bigger than it did without the lens. Show how to
solve for X. (You do not need to use F to get the answer.) Hint:
think about how the magnification changes. B) Set up equations that
would allow you to determine F. Solve them for extra credit.
