Focal length equation thin lens
WebThe focal length of the lens is {eq}f=5cm {/eq}. The positive focal length is an indication that the lens is converging. Example 2. An object is placed 1 centimeter to the left of a … WebSep 12, 2024 · The focal length f of the magnifying lens may be calculated by solving Equation 2.8.8 for f, which gives M = 1 + 25cm f f = 25cm M − 1 = 25cm 5.0 − 1 = 6.3cm b. To get an image magnified by a factor of ten, we again solve Equation 2.8.8 for f, but this time we use M = 10. The result is f = 25cm M − 1 = 25cm 10 − 1 = 2.8cm. Significance
