Two thin lenses with a focal length of magnitude 12.0 cm, the first diverging and second converging, are located 9.00cm apart. An object 2.50mm tall is placed 20.0cm to the left of the first (diverging) lens. Note that focal length of diverging lens is a negative number while focal length of converging lens would be positive.

a) Draw a figure showing both lenses and use principal rays to find approximate position of the image formed by the first lens.

b) Calculate how far from this first lens is the first image formed.

c) Calculate how far from this first lens is the final image formed.

d) What is the height of the final image?

e) Is it upright or inverted?
