SUMMARY
The discussion centers on the optical behavior of two lenses: a diverging lens with a focal length of -31.5 cm and a converging lens with a focal length of 20.0 cm, positioned 14 cm apart. To determine where an object at infinity is focused, one must first calculate the image produced by the diverging lens using the lens formula. This image serves as the virtual object for the converging lens, and the distance of 14 cm is crucial for determining the object distance for the converging lens, ultimately leading to the calculation of the final image distance.
