Question

the magnification produced by a plane mirror is +1 what does it mean
​

Answer 1

Answer:

Magnification:

Magnification produced by a spherical mirror gives the relative extent to which the image of an object is magnified with respect to the object size. It is expressed as the ratio of the height of the image to the height of the object. It is usually represented by the letter m.

$\sf{Magnification \:= \:} {\dfrac{hi}{ho}} {=} {\dfrac{-v}{u}}$

The magnification produced by a plane mirror is +1 means then the size of the image is equal to the size of the object. If m has a magnitude greater than 1 the image is larger than the object, and an m with a magnitude less than 1 means the image is smaller than the object.
