Question

can any one can explain the magnificatio of mirror

Answer 1

hey genious here is your answer
the magnification of mirror is ratio of height of image to the height of object

Answer 2

which mirror?
please make it clear whether it is plane, concave or convex mirror.

Magnification is the increase in the image size produced by spherical mirrors with respect to the object size. It is the ratio of the height of the image to the height of the object and is denoted as m. The magnification, m produced by a spherical mirror can be expressed as:

m=h/h′

Here, h is the height of image and h’ is the height of the object.

Magnification is also equal to the ratio of image distance to the object distance.

m=v/u

A plane mirror does not change the size of the (virtual) image reflected from it. Therefore, the magnification is 1.
