WebThe focal length f of the magnifying lens may be calculated by solving Equation 2.30 for f, which gives M = 1 + 25 cm f f = 25 cm M − 1 = 25 cm 5.0 − 1 = 6.3 cm To get an image magnified by a factor of ten, we again solve Equation 2.30 for f, but this time we use M = 10. The result is f = 25 cm M − 1 = 25 cm 10 − 1 = 2.8 cm.
