Question

Q7. Assertion: Magnification of a real image is positive but magnification of a virtual image is negative. Reason: Real image is an inverted image but virtual image is an erect image​

Answer 1

Answer:

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.
