Two thin lenses with focal lengths of magnitude 15.0 cm, the first diverging and the second converging, are placed 12.00 cm apart. An object 5.00mm tall is placed 4.50cm to the left of the first (diverging) lens.
a.) Where is the image formed by the first lens located?
b.) How far from the object is the final image formed?
c.) Is the final image real or virtual?
d.) What is the height of the final image?
e.) Is the final image erect or inverted?
