An object is placed between infinity and the pole (P) of a convex mirror. The image is positioned

For a convex mirror, regardless of the position of the object (whether placed between infinity and the pole), the image is always formed between the pole (P) and the focus (F), behind the mirror. The image formed by a convex mirror is always virtual, erect, and diminished. This is because the parallel rays after reflection from a convex mirror appear to diverge from the focus behind the mirror, so the image always lies between P and F behind the mirror. This property makes convex mirrors useful as rear-view mirrors in vehicles and security mirrors in shops, as they provide a wide field of view.
