The Magnification Produced by a Plane Mirror is +1. What does this mean?

By K Balaji|Updated : November 12th, 2022

The magnification produced by a plane mirror is +1. It means that both the image distance and object distance are equal.

  1. The ratio of the image's size to the object's size, or the "magnification," created by a mirror is defined as follows: m = hi/h0
  2. A positive magnification created by a mirror indicates a virtual picture, while a negative magnification produced by a mirror indicates a genuine image.
  3. A planar mirror produces a magnification that is +1, that is +1 = hi/h0 → h0 = hi
  4. As a result, the image size created matches the object size behind the mirror perfectly.
  5. Positive magnification denotes a virtual and upright image.
  6. It is known that, magnification m = -v/u i.e., +1 = -v/u → -u = v
  7. This indicates that the distance of image and the distance of object are equal.

Uses of Magnification

  • A precision magnifier performs the same function as a standard magnification but contains additional components that help to remove aberrations and provide sharper images.
  • A water droplet serves as a straightforward magnifier, enlarging the object behind it. The effect of surface tension causes the water to condense into spherical droplets. A spherical shape is distorted but still capable of generating an image when the droplet comes into contact with an object.

Summary:-

The Magnification Produced by a Plane Mirror is +1. What does this mean?

A plane mirror produces a +1 magnification. It indicates that the object distance and picture distance are same.
