A doctor examines a mole with a 15.6 cm focal length magnifying glass held 11.7 cm from the mole.
(a) How far is the image from the lens?
Can you write the thin lens equation which gives a relationship
between the focal length of a lens, the object distance, and the
image distance? If the image distance is negative, what can you
conclude about the image? cm
Is the image real or virtual?
realvirtual
(b) What is its magnification?
(c) How big is the image of a 5.00 mm diameter mole?
mm
