Unformatted text preview: length 6 cm. 4) A lightbulb is placed at x = 0 cm on an optical bench. A diverging lens of unknown focal length is placed at x = 15 cm. A converging lens of focal length 10 cm is placed at x = 45 cm. A screen is placed at x = 60 cm and shows a wellfocused image of the light bulb filament. A) What is the focal length of the diverging lens? B) What is the lateral magnification of the image? C) Is the image upright or inverted? 5) A converging lens is used to form an image at s of an object at s . Suppose the object has finite thickness; i.e. it extends from s to s + ds . Show that the longitudinal magnification of the object ds / ds = M 2 , where M = s / s is the lateral magnification....
