Which mirror has a wider field of view?
$$\large \textbf{Concept used:}$$
Uses of convex mirrors.
$$\large \textbf{Explanation:}$$
$$\bullet$$ As we can see from the diagram, $$convex \ mirrors$$ have a wider field of view as they are curved outwards.
$$\bullet$$ Thus, convex mirrors are used as rearview mirrors as they enable the driver to view a much larger area than would be possible with a plane mirror.
On the other hand,
$$\bullet$$ Plane mirror and concave mirror don't have much wide field of view.
$$\bullet$$ Concave mirrors are converging mirrors so they have the minimum field of view.
