A physics student places an object 6.0 cm from a converging lens of focal length 9.0 cm. What is the magnitude of the magnification of the image produced?
0.6
2.0
3.6
3.0

inverted and larger
A group of students collected data using a lens. They varied the distance so of an object from the lens and measured the image distance si. The figure above is their graph of the inverse of the image distance as a function of the inverse of the object distance. The focal length of the lens is approximately
2.0 m
