Barbara places an object in front of a mirror. The mirror produces an image that is inverted, real, and smaller than the object. Which kind(s) of mirror could Barbara be using?

A real, inverted image can be produced by a concave mirror when the object is beyond the mirror’s focal point. A plane mirror always makes an upright, virtual image, and a convex mirror also makes an upright, virtual image. Therefore, the mirror must be concave; choice C is correct.
