Problem 3
A thin converging lens has focal length . A real object of height is placed a distance from the lens. Find the signed image distance , magnification , image height, and whether the image is real or virtual. Model each stage with the appropriate conservation law or equation of motion; quantities stated as constant remain fixed during that stage. (a) Establish the governing physical relation for each stage. (b) Determine the requested observables from the stated initial conditions and constraints. (c) Check signs, dimensions, and the physical limiting behavior of the results.
