A converging lens (f = 12.6 cm) is held 8.55 cm in front of a newspaper, the print size of which has a height of 2.10 mm.

(a) Find the image distance (in cm),

(b) The height (in mm) of the magnified print.

• physics -

(a) Use 1/do + 1/di = 1/f
with f = 12.6 and do = 8.55
Solve for di (image distance)

(b) Image height = 2.1 mm * di/do
