Answer:
The magnification, m produced by a spherical mirror can be expressed as:
m=h′/h where h′ is height of image and h is height of object.
It is also equal to the negative of the ratio of the image distance(v) to object distance (u).
m=−v/u
Explanation:
Magnification helps us in judging the size of the image formed in comparison to that of the object. It tells us whether the image formed is magnified, diminished ,equal to object when object is placed at different positions on the principal axis.
In the case of a mirror, real images are formed in front the mirror and virtual images are formed behind the mirror.
