Solution

Definition

Magnification means the expansion in image size caused by spherical mirrors in relation to the size of the object. It is the proportion of the image's height(hi) to the object's height(ho).

m=vu=hiho

Mirror formula,

The mirror formula can be represented as:

1f=1v+1u

Here,

f is the focal length of the mirror.

u is the object distance (distance of the object from the mirror).

v is the image distance (the distance the image is formed from the mirror).
