what is magnification ?derive the formula for magnification of spherical mirror​

Answer 1

Answer:

Magnification is the process of enlarging the apparent size, not physical size, of something. This enlargement is quantified by a calculated number also called "magnification".

Magnification is also equal to the ratio of image distance to the object distance. As the object is always above the principal axis, the height of the object is always positive.
