We draw first point A’ which is the image of point A, we placed it one unit away from the mirror, then points B’ and C’ are placed with the same way. The size of the object equals to that of the size of the image. The image formed by a plane mirror is always virtual (meaning that the light rays do not actually come from the image), upright, and of the same shape and size as the object it is reflecting.A virtual image is a copy of an object formed at the location from which the light rays appear to come. Here is the list of characteristics of an image formed by a plane mirror. (iii) A virtual and erect image is formed. Characteristics of the image formed by a plane mirror : It is virtual; It is erect and of the same size as the object; The distance of the object from the plane mirror is the same as the distance of the image from the plane mirror. Images Formed by Plane Mirrors [Image to be added Soon] The nature of the image formed by a plane mirror is mentioned below: The image is virtual and erect. It can only be seen by looking into the mirror. In plane mirrors always virtual image is formed. Distinguish between real and virtual images. (i) The size of the image is the same as the size of the object. Describe how an image is formed by a plane mirror. An image is formed behind the mirror. In this context we call the virtual image a virtual object. As I said before, image of the object is formed behind the mirror with the same distance of object. You only have to look as far as the nearest bathroom to find an example of an image formed by a mirror. Example: Find the image of the given object. A virtual image cannot be formed on a screen. (ii) The distance of the object in front of the mirror is equal to the distance of the image behind the mirror. In order for a plane mirror to produce a real image ir must be reflecting the virtual image produced by another mirror or a lens. The image in a plane mirror is not magnified (that is, the image is the same size as the object) and appears to be as far behind the mirror as the object is in front of the mirror. One of the important characteristics of the image is that it is laterally inverted. Find the location and characterize the orientation of an image created by a plane mirror. (iv) The image formed by a mirror is laterally inverted. A diverging lens (one that is thicker at the edges than the middle) or a convex mirror forms a virtual image. The image appears to be behind the mirror.
