For the image formation by a convex mirror in this condition, we consider two rays parallel to the principal axis and one directed towards the pole of the mirror originating from the object. These rays after reflection form an image at F, the principal focus of the mirror, which is behind the convex mirror.
When The Object is Placed Between Infinity and Pole
In this situation of the image formation by a convex mirror, we consider two different rays emerging from the object. One parallel to the principal axis and the other directed towards the centre of curvature of the mirror. These rays after reflection form an image between the pole (P) and the focus (F) behind the mirror. The image thus formed is diminished, virtual and erect.
Convex lens image when Object is Placed Between Infinity and Pole
Position of the object Position of the image Size of the image Nature of the image
At infinity At focus, F, behind the mirror Highly diminished and pointed in size Virtual and erect
Between infinity and pole of the mirror Between P and F, behind the mirror Diminished Virtual and erect
Uses of Convex Mirrors
Because they have wider fields of view, as they are curved outwards they are commonly used in automobile side mirrors.
Convex mirrors are also a good security device because single security personnel could see large portions of the store while monitoring from a single location.
They are used in driveways and roads, to provide safety to all the bikers and drivers at curves and other places where there is a lack of visibility.
They are also used in ATMs as a handy security feature that allows the user to see what is happening behind them.
