An object which is 1.23 cm high is placed 10.00 cm to the left of a lens. It is not known if the lens is converging or diverging. An image forms 3.20 cm to the left of the lens. (a) Determine if the lens is converging or diverging by calculating the focal length of the lens. (3) (b) Calculate the height of the image. (1) (c) Describe the image. Is it real or virtual, upright or inverted and enlarged or diminished?
