Question

What is magnification
? How it is related to 'u' and 'v'?

Answer 1

magnification is the ratio of height of the image and height of the object

also, m = v/u

Answer 2

We consider m = -v/u for mirrors, considering you are using the convention of left side of the mirror/lens to be negative, and below the principal axis to be negative … rest implied.

Hence, we consider m = v/u for lens with the aforementioned convention.
