Question

If the magnification of the image formed by the mirror. What does it mean

Answer 1

Negative magnification :- Negative magnification indicates that both object and image formed have different orientations. If the object is erect then the image formed by a spherical mirror (concave or convex) is inverted. An inverted image is always real. Thus, negative magnification means that the image formed by a spherical mirror is real. Positive magnification :- It means that both the object and the image formed by a spherical mirror (concave or convex) are erect (I.e., upright). An erect image is always virtual. Thus, positive magnification indicates that the image formed by a spherical mirror is virtual. Linear magnification (m) :- linear magnification produced by a mirror is the ratio of the size of the image formed (denoted by h') to the ratio of the size of the object
