Which property of convex mirrors makes them suitable for use in shopping malls for security purposes?
They give a wide field of view.
A convex mirror diverges reflected light and always forms a virtual, erect and diminished image.
Because the image is diminished, a large area fits into a small mirror, giving a much wider field of view than a plane mirror of the same size.
That is why convex mirrors are fixed at corners of malls and shops for surveillance, and as rear-view mirrors in vehicles.
They do not magnify (images are smaller), they do not reflect light into parallel beams (concave mirrors do that with a source at the focus), and lateral reversal is not the feature that suits them for security.
Hence, the answer is They give a wide field of view.
