- Two lenses are placed along an optical rail. One is a converging lens, with a focal length of f1 = 30.3 cm. The second lens, a diverging lens with a focal length of f2 = −20.0 cm, is placed d = 110 cm to the right of the converging lens. An object ho = 2.02 cm high is placed p1 = 40.5 cm to the left of the converging lens. (a) Determine the position of the final image. (Enter the position in cm relative to the diverging lens.) magnitude ? cm direction right or left? of the diverging lens (b) Determine the magnification of the final image. (Indicate the orientation with the sign of your answer.) Hint* The total magnification is the product of each individual magnification. (c) Is the image upright or inverted? (d) Repeat parts (a) through (c) for the case in which the second lens is a converging lens having a focal length of 20.0 cm. (Enter the position in cm relative to the second lens.

Double check your calculations. cmIn a two-lens system, the focl length of the lens is f1 = 4.00 cm, and that of then lens 2 is f2 = 8.00 cm. The distance between the lenses is 16 cm. If an object O is 2.00 cm high and is placed 6.00 cm in front of the lens 1, where is the final image through the two-lens system?

(Neglect the distance from the lens to the eye.) (a) focal length (in cm) of the appropriate corrective lens cm (b) power (in diopters) of the appropriate corrective lens dioptersA 1.00-cm-high object is placed 3.95 cm to the left of a converging lens of focal length 7.80 cm.
