Consider two statements A and B given below:A: real image is always invertedB: virtual image is always erectOut of these two statements:(a) only A is true (b) only B is true (c) both A and B are true (d) none is true
(c) both A and B are true
Explanation
A real image occurs when light rays converge, whereas a virtual image occurs when light rays only appear to converge.
A real image is always formed below the principal axis, so these are always inverted, whereas a virtual image is always formed above the principal axis, so these are always erect.
The real images can be produced by concave mirrors and convex lenses (converging lens), and it happens only if the object is placed farther away from the mirror/lens than the focal point.
On the other hand, a virtual image is always produced by plane mirrors, convex mirrors, and concave lenses (diverging lens).
