  1. Concave mirrors are used for headlights as it gives larger area of magnification for the light.
  2. The mirror which is preferred as rear-view mirror in cars and motorcycles is the convex mirror because the image obtained with the help of convex mirror is highly diminished in size and thus gives a wider field of view and helps the driver of the vehicle to view the traffic in much larger area behind the vehicle.
