WebPractice Problems. As a demonstration of the effectiveness of the lens equation and magnification equation, consider the following sample problem and its solution. Sample … 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

Since three of the four quantities in the equation (disregarding the M) are known, the fourth quantity can be calculated. The solution is shown below. h i /h o = - d i /d o h i / (4.0 cm) = - (-18.2 cm)/ (8.3 cm) h i = - (4.0 cm) • (-18.2 cm)/ (8.3 cm) hi = 8.8 cm book the speed of trustWebMagnification = Basic calculations 1.
