Question

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

Answer 1

Answer:

it means that the size of image and object is same

we know, magnification = height of image/height of object

when they are same, m = height of image/height of object

m =+1

Answer 2

Hey there!

Magnification is the ratio of height of the image to height of the object.

So,

According to the question,

Magnification of images produced by a plane mirror is 1 ,

So,

Height of the image / Height of the object = 1 ,

Now,

Height of the image = Height of the image.

We can conclude that, A plane mirror forms a image which is of the same size as object.
