-- A concave mirror produces an enlarged virtual image when the object is placed between the mirror and its focal point (Region 3).-- If an object is placed 4.1 cm from a concave mirror with f = 4 cm, then its image will be reduced and real.-- If an object is placed 7.9 cm from a concave mirror with f = 4 cm, then its image will be enlarged and real.-- A convex mirror produces an enlarged virtual image when the object is placed far beyond its focal point (Region 1).-- If an object is placed 4.1 cm from a convex mirror with f = 4 cm, then its image will be enlarged and real.-- If an object is placed 7.9 cm from a convex mirror with f = 4 cm, then its image will be enlarged and virtual.-- The magnification m is negative for upright images.-- Virtual images appear behind a mirror and have a positive value for the image distance.-- Real images appear in front of a mirror and have a negative value for the image distance.
