Question

Assertion : Magnification of a convex mirror is always positive, but that of a concave mirror may be both positive or negative.

Answer 1

The sign of magnification depend on the sign convention chosen. According to the new Cartesian sign conventions, magnification for a convex mirror is positive because image formed by a convex mirror is always virtual and erect. A concave mirror can form virtual or erect images and also real, inverted images. In the latter case, its magnification becomes negative.
