Question

1.Name a mirror that can give an erect and enlarged image of an object.
2.Why do we prefer a convex mirror as a rear-view mirror in vehicles?
​

Answer 1

1.Concave mirror gives an erect and enlarged image of an object, when the object is between pole (P) and principal focus of mirror (C)

2.Convex mirrors are commonly used as rear-view (wing) mirrors in vehicles because they give an erect, virtual, full size diminished image of distant objects with a wider field of view. Thus, convex mirrors enable the driver to view much larger area than would be possible with a plane mirror.
