Two identical diverging lenses are separated by 6.0 cm. Each lens has a focal length of -12 cm. An object is placed 10 cm in front of the first lens. (a) Use ray tracing to determine the location of the final image and report from your diagram whether the final image is real or virtual, if it's upright or upside-down, and approximate its magnification. Use a ruler and be as accurate as possible. Mathematically find (b) the location and (c) the magnification of the final image produced by this lens combination. the object is 10 cm in front of the first lens. And note that I'm asking about the final image, not the intermediate image.
