The optical system consists of converging and diverging lenses adjacent to one another, the main optical axes of which coincide. The focal lengths of the collecting and diverging lenses are F1 = 50 cm and F2 = - 0.80 m. Find the position of the image of the luminous point, which is located on the optical axis of the system at a distance d = 80 cm from the optical center. What image will it be?
