object distance is the distance between the object and the
principal focus or the centre of the mirror or lens. The position of object determine
the type of image formed on both mirror and lenses. Plane mirror has their
object distance between distance equal to their image distance, convex
lens has same type of image no matter
the position of the object. While concave mirror has varying images depending on
the position of the object. Diverging lens as same type of images no matter the
position of the images while converging lens has varying images depending on
the object distance.
