Answer 2

Answer:

Explanation:

1. Pole is considered as the origin
2. Object is always placed in the left side of the mirror
3. All distances parallel to the principal axis are measured from the pole of the mirror
4. distance along the incident ray are taken +ve and against are taken -ve

     5. distance measured above the principal axis is taken as +ve , and below       the principal axis are taken -ve

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". When this number is less than one, it refers to a reduction in size, sometimes called minification or de-magnification

The magnification produced by a plane mirror is +1 means that the image formed is virtual, erect and of the same size as that of object.

concave mirrors have positive f and convex mirrors have negative f. for magnification, positive values indicate that the image is the same orientation as the object (object upright, image also upright), negative if the image is inverted relative to the object.
