Is the magnification of the image formed by the convex mirror always -ve if yes how. if no how.

Dear Student

Using sign conventions, in case of convex mirrors we can write,

Object distance = -u
Only virtual images are formed, hence image distance is always +v

Hence the magnification for virtual images in convex mirror given as,

.

will always be postive.

We hope that clarifies your doubt.
