WebDec 16, 2024 · The focal point of a plus lens occurs where parallel light rays that have passed through the lens converge to form an image. The focal point of a minus lens occurs where parallel light rays entering the lens appear to diverge. WebTwo lenses are placed along the x axis, with a diverging lens of focal length 8.00 cm on the left and a converging lens of focal length 16.0 cm on the right. When an object is placed 10.0 cm to the left of the diverging lens, what should the separation s of the two lenses be if the final image is to be focused at x = ?
