Question

The distance between an object and its image formed by a diverging lens is

8.0 cm. The focal length of the lens is -3.0 cm. Find the image and object
distances.

Answer 1

Image distance: object distance + focal length or, 8.0 + 3.0 so 11.0cm

Object distance: image distance - focal length or 11.0 - 3.0 so 8.0cm
