Focal length and magnification formula

WebTo find the position and magnification of the final image, we can use the formula for the lens equation: 1 f = 1 d o + 1 d i where f is the focal length of the lens, d o is the distance of the object from the lens, and d i is the distance of the image from the lens. WebAs a demonstration of the effectiveness of the lens equation and magnification equation, consider the following sample problem and its solution. Sample Problem #1 A 4.00-cm tall light bulb is placed a distance of 45.7 cm from a double convex lens having a focal length of 15.2 cm. Determine the image distance and the image size.
