Answer :
1. concave mirror
because A concave mirror is used in the headlights of a car. a simple explanation for this would be: when a lighted bulb is placed at the focus of a concave mirror reflector, the diverging light rays of the bulb are collected by the concave reflection and then reflected to produce a string, parallel beam of light.
2.convex mirror
because The side mirrors of the car and the rear view mirror of a car are made up of convex mirrors. This is because the image formed by a convex mirror is diminished and erect image, thus it provides a larger field of view. A larger field of view helps the driver to know better about the traffic behind.
3.Concave mirrors
because Concave mirrors are used in solar furnaces, because concave mirrors are the only type of mirror that reflects light in toward a single focal point. A flat mirror does not have a focal point. It does regular reflection off all of its points.
i) Headlights of a car : Concave mirror
ii) Rear-view mirror of vehicle : Convex mirror
iii) Solar furnace : Concave mirror
