In the below diagram, an object is kept far away from the convex mirror (almost at an infinite distance), helping to draw rays parallel to the principal axis. As the below infinity convex diagram suggests, the Convex mirror is used in the rearview mirror of vehicles; so that the driver can see the traffic coming from behind. The field of view is widest in the case of a convex mirror, which enables it to show a wider area from behind. A convex mirror is used on hairpin bends on the road; so that the driver can see the traffic approaching from another side of the bend.
