A small linear object of length I is placed along principal axis of a concave mirror. The neartest point the object is at a distance d from the mirror. If focal length of the mirrors is f then, prove that the size (length) of the image will be l((f)/(d-f))^(2)

A short linear object of length b lies along the axis of a concave mirror of focal length f at a distance u from the pole. What is the size of the image?
