A jeweler examines a diamond with a magnifying glass. If thenear-point distance of the jeweler is $22.8 \mathrm{cm},$ and the focal lengthof the magnifying glass is $7.70 \mathrm{cm},$ find the angular magnification when the diamond is held at the focal point of the magnifier,Assume the magnifying glass is directly in front of the jeweler's eyes.

So in order to solve this problem, we just need to know that when a Diamandis place of the focal point of a magnifying bless the magnified image will be created at infinity. So knowing this, we know that equation we need to use. It's just an divided by F, and the problem gives us what is the near point and what is Defoe Kel lent off the magnifying glass. So the new point the problem tells us, is 22 0.8 centimeters and the focal lens. The problem tells us that a seven point seven think team enters. So the magnification, the angler magnification just going to be to a point 96 to dis glass.
