A stamp collector observed his favorite stamp with a magnifying glass with a focal length of 24.0 cm. The image of the stamp was located at his near point distance of 30.0 cm. What was the approximate angular magnification of the magnifying glass when the collector observed his stamp?
Homework Answers
he equation to use is the magnification (M) = 1 + near point
(N)/focal length (f)
M = 1+ 30/24
M = 2.25

A jeweler examines a diamond with a magnifying glass. If the near-point distance of the jeweler is 20.7 cm, and the focal length of the magnifying glass is 7.00 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. (Include the sign.) ✕ A grade-school student plans to build a 55 power telescope as a science fair project. She starts with...
