Problem
A small convenience store wants a ceiling-mounted mirror that allows a cashier to view as much of the sales floor as possible while customers see upright images of themselves. Which mirror choice best satisfies these requirements?
(a) A plane mirror mounted horizontally on the ceiling, because a flat surface preserves orientation and therefore shows the whole store
(b) A convex spherical mirror, because it produces upright, reduced images that include a wider field of view
(c) A concave spherical mirror with the aisles placed inside its focal length, because it produces upright, enlarged images that seem to cover a wider area
(d) A concave spherical mirror positioned far beyond its center of curvature, because it produces reduced, inverted images over a broad viewing angle
