Problem
A short straight object of height 100 cm lies before the central axis of a spherical mirror whose focal length has absolute value ∣f∣=40 cm. The image of the object produced by the mirror has height 25 cm and has the same orientation as the object. One may conclude from the information:
(1) Image is real, on the same side of a concave mirror.
(2) Image is virtual, on the opposite side of a convex mirror.
(3) Image is virtual, on the opposite side of a concave mirror.
(4) Image is real, on the same side of a convex mirror.
