1a) Prove that, for a concave mirror, the ratio of object to image distance is the same as that of object to image height

1b) The normal human eye can focus on objects at distances ranging from 25 cm to infinity. The distance from lens to the back of the retina, where the image needs to be formed, is about 1.7 cm. What is the range of focal lengths of the lens of the eye?
