Question

State the characteristics of the image formed by a plane mirror.

Answer 1

Hint:Firstly, we will place an object in front of the plane mirror, then try to observe and then only judge the image formed by that plane mirror. Then, discuss each of the characteristics of the image formed by the plane mirror.

Complete answer:
The characteristics or the properties or the nature of the image formed by a plane mirror are as follows:
(1.) The image is upright or erect in nature: An erect image, in optics, is one that appears right-side up. An erect image is formed when both rays intersect each other at a certain point. It is an image in which directions are the same as those in the object, in contrast to an inverted image. It is one of the properties of images formed in a plane mirror.
(2.) The image is equal to the object in the size: The size of the image formed by a plane mirror is the same as that of the size of the object. If an object is 10 cm high, then the image of this object will also be 10 cm high. The image formed by a plane mirror is at the same distance behind the mirror as the object is in front of it.

(3.) The image is laterally inverted (reversed): We already know that the image in a mirror is. Behind the mirror (Virtual) Equal distance same size Upright. But perhaps we should add one more criteria: Laterally inverted.
(4.) The image cannot be received on a screen as it is virtual: For plane mirrors, you can't get the virtual image on a screen by putting the screen behind the mirror. The image that structures on your retina is the genuine picture of the "virtual object" behind the mirror.

Note: Plane mirror never forms a real image as plane mirrors are the only type of mirror for which a real object always produces an image that is virtual, erect and of the same size as the object. Virtual objects produce real images, however. The focal length of a plane mirror is infinity; its optical power is zero.
