Two-lens optical system showing object, lenses, and intermediate focal point P.
Two-lens optical system showing object, lenses, and intermediate focal point P.
In an optical setup, a converging lens with focal length \(f_1 = +20\text{ cm}\) is placed \(60\text{ cm}\) to the right of an illuminated object, forming a real intermediate image at a point \(P\). A diverging lens with focal length \(f_2 = -30\text{ cm}\) is then inserted along the optical axis, positioned \(20\text{ cm}\) to the right of the converging lens (which is \(10\text{ cm}\) before the converging rays reach point \(P\)). What is the location and nature of the final image produced by this two-lens system relative to the diverging lens?
