-----------------------
Place an object (rose, light bulb) inverted and at the distance of the radius of curvature from a concave mirror (Positive s since on the side of the incident light). The resulting image is real (on the side of the reflected/refracted light) and inverted (m = -p/s), i.e. now upright and just above the original object. If the object is obscured by being placed in a box, the real image appears above the box with good "Magical" effect.


1/s + 1/p = 2/R
