The magnification produced by a mirror is -1/2 Find nature and position of the object

Explanation:
Mirror Formula
Now, that all these conventions are clear; let us know move on the mirror formula. Mirror Formula helps us to find:
a. Image distance which is represented as ‘v’.
b. Object distance which is represented as ‘u’.
c. Focal length which is represented as ‘f’.
And is written as :
1/v + 1/u = 1/f
This formula is valid for all kinds of spherical mirrors, for all positions of the object. Although one needs to be careful about the values, one puts for u,v and f with appropriate sign according to the sign convention given above.
Physically, we all understand what is magnification. It can be defined as the extent to which the image appears bigger or smaller in comparison to the object size.
It is represented as the ratio of the height of the image to the ratio of the height of the object. Magnification is denoted as the letter ‘m’. Where,
Magnification (m) = h/h’
And h’ is the image height and h is the object height.
Magnification can also be related to the image distance and object distance; therefore it can also be written as:
m = -v/u
Where v is the image distance and u is the object distance.
Hence, the expression for magnification (m) becomes:
m = h’/h = -v/u
Hope this helps mate ☺️.
