Question

the magnification produced by a plane mirror is +1. what does this mean???​

Answer 1

Answer:

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.

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.
