Answer 2

$\Large\bold \red{Question:}\Rightarrow$

A convex mirror is used as a side rear view mirrors in cars.

$\huge\bold{\mathtt{\purple{A{\pink{N{\green{S{\blue{W{\red{E{\orange{R}}}}}}}}}}}}}$$\huge \Rightarrow$

(1) When an object is kept in front of a convex mirror, we get an erect and minished image of the object. (2) Thus, the convex mirror fitted by the side of a car driver, enables him to get an erect, clear and complete view of the vehicles coming from behind. Hence, a convex mirror is used as a rear-view mirror in a car.
