Using a thin lens with a focal length of f =+5.2cm, a student makes two measurements. She finds the distance to the object to be o =+3.1cm. What distance, i, should she expect for the image? Describe whether this is a real or virtual image using the sign convention. Then discover the magnification of the image too explaining your answer using the sign convention.
