Leah looks in her physics book and finds that the thin-lens equation can be used to relate the image distance and object distance for a thin lens, and is given by 1 p + 1 q = 1 f . The lateral magnification of the image is given by M = h' h = q p . To use these equations, Leah and Arif must understand the sign conventions and spend a few minutes discussing the sign conventions used. Which of Leah's statements is false? "f is positive for a converging lens and negative for diverging lens." "Image is inverted when h' is positive and upright when h' is negative." "Image distance is positive if the image is in back of the lens and negative if the image is in front of the lens." "The object distance is positive for an object in front of the lens and negative when the object is in back of the lens
