You plan to project an inverted image 30.0 cm to the right of an object. You have a diverging lens with focal length -4.00 cm located 6.20 cm to the right of the object. Once you put a second lens at 18.8 cm to the right of the object, you obtain an image in the proper location.
(a) What is the focal length of the second lens (cm)?
(b) Is this lens converging or diverging?
(c) What is the total magnification?
(d) If the object is 12.0 cm high, what is the image height?
