A concave spherical mirror and a convex spherical mirror each have a radius of curvature of magnitude \(R\). An upright object of height \(h\) is placed at a distance \(d = R\) along the central optical axis in front of the concave mirror, forming an image of height \(h_{\text{concave}}\). The same object is then placed at a distance \(d = R\) along the central optical axis in front of the convex mirror, forming an image of height \(h_{\text{convex}}\). What is the ratio \(\dfrac{h_{\text{concave}}}{h_{\text{convex}}}\) of the heights of the two images?
