Question

magnification of convex mirror is +ve or -ve??

its mirror not lens ​

Answer 1

Answer:

magnification of convex lens is always positive.

Explanation:

Reason :

A convex lens always forms virtual images for all positions of object.

∴ Image is always formed behind the mirror.

↦ image distance v = (+)ve

↦ object distance u = (-) ve

⇒ m = -v/u = - (+ve)/(-ve)

= ( + ) ve
