Which of the following statements about image formation by spherical mirrors is NOT correct?
A real image is always erect.
A real image is formed where reflected rays actually meet, and it can be obtained on a screen. For a spherical mirror, a real image is always formed in front of the mirror and is always inverted. So the statement that a real image is always erect is NOT correct.
The other statements are correct. A concave mirror forms a virtual, erect and magnified image when the object is placed between the pole and the principal focus.
A concave mirror forms a highly magnified (enlarged) real image when the object is placed between the focus and the centre of curvature, the image becoming very large as the object approaches the focus.
A convex mirror always forms a virtual, erect and diminished image, whatever the position of the object, which is why it is used as a rear-view mirror.
Hence, A real image is always erect.
