An object placed midway between a coaxial concave mirror and convex mirror.
An object placed midway between a coaxial concave mirror and convex mirror.
A concave mirror and a convex mirror, each having a focal magnitude \(f\), are placed coaxially facing each other separated by a distance \(2d\), where \(d > f\). A small object is placed on the principal axis midway between the two mirrors, at a distance \(d\) from each mirror. The mirrors form primary images directly from light emitted by the object. Which row in the table correctly identifies the ratio of the magnitudes of the primary image distances, \(\left|\dfrac{d_{i,\text{concave}}}{d_{i,\text{convex}}}\right|\), and the relative orientation of the two primary images?

RowRatio of Image DistancesRelative Orientation
A\(\dfrac{d - f}{d + f}\)Inverted relative to each other
B\(\dfrac{d - f}{d + f}\)Same orientation as each other
C\(\dfrac{d + f}{d - f}\)Inverted relative to each other
D\(\dfrac{d + f}{d - f}\)Same orientation as each other
