Focal length equation thick lens
WebSubstitute l = 3l’ and f’ = -20 cm in the lens equation. We get l’ = -13.3 cm and l = -40 cm. Q. An object 8 cm high is placed 12 cm to the left of a converging lens of focal length 8 cm. A second converging lens of focal length 6 cm is placed 36 cm to the right of the first lens. Both lenses have the same optic axis.
