Q1. Which mirror will show a wide-area view?
Explanation
A convex mirror gives a wider field of view because its reflecting surface bulges outward and forms diminished, erect images of objects spread over a larger area. That is why it is used as a rear-view mirror in vehicles and for surveillance at turns. A plane mirror gives an image of the same size and has a limited field. A concave mirror can magnify or focus light, so it is not suited for wide-area viewing. A parabolic mirror is mainly used to focus parallel rays, as in headlights or reflectors.
