Answer 1

it is defined as the ratio of the size of the image to the size of the object.
m= -v/u or m=h'/h where v means image distance and u means object distance
h'means size of the image or h means size of the object

Answer 2

Magnification (m) = h/h' And h' is the image height and h is the object height.Magnification can also be related to theimage distance and object distance; thereforeit can also be written as: m = -v/u.
