(i) headlights and

Concave mirrors are used for headlights as it gives larger area of magnification for the light. Convex mirrors give a virtual, erect and diminished image of the objects placed in front of them. They are preferred as a rear-view mirror in vehicles because they give a wider field view, which allows the driver to see most of the traffic behind him.
