The characteristics of an image formed in a plane mirror:. Last updated on Feb 13,

You only have to look as far as the nearest bathroom to find an example of an image formed by a mirror. Images in a plane mirror are the same size as the object, are located behind the mirror, and are oriented in the same direction as the object i. Note that we use the law of reflection to construct the reflected rays. By forming images of all points of the object, we obtain an upright image of the object behind the mirror. Notice that the reflected rays appear to the observer to come directly from the image behind the mirror.

In the case of plane mirrors, the image is said to be a virtual image. Virtual images are images that are formed in locations where light does not actually reach. Light does not actually pass through the location on the other side of the mirror; it only appears to an observer as though the light is coming from this location. Whenever a mirror whether a plane mirror or otherwise creates an image that is virtual, it will be located behind the mirror where light does not really come from. Later in this unit , we will study instances in which real images are formed by curved mirrors. Such images are formed on the same side of the mirror as the object and light passes through the actual image location. Besides the fact that plane mirror images are virtual, there are several other characteristics that are worth noting. The second characteristic has to do with the orientation of the image. If you view an image of yourself in a plane mirror perhaps a bathroom mirror , you will quickly notice that there is an apparent left-right reversal of the image. That is, if you raise your left hand, you will notice that the image raises what would seem to be it's right hand.

Two parallel mirrors can produce, in theory, an infinite number of images of an object placed off center between the mirrors.

When a light ray falls on a surface, then it can undergo one of the three phenomena, namely, reflection, refraction, and absorption. Most of the light gets absorbed when a ray of light falls on a normal surface. Therefore, we can say that mirrors are polished surfaces, which are coated with Mercury chemical symbol Hg so that they can reflect most of the light that falls upon them. We can classify mirrors as a convex mirror, concave mirror, or a plane mirror, based on the reflecting surface. For forming an image with the help of a plane mirror, we require at least two rays of light from an object that either meet or appear to meet at a point. So, let's make ourselves familiar with the concepts of a plane mirror, along with its characteristics, uses, and applications. A real image is an image that is produced either due to reflection or refraction when the ray of light arises from an object and then converges to a certain point.

Images in a plane mirror are the same size as the object, are located behind the mirror, and are oriented in the same direction as the object i. To understand how this happens, consider Figure. Note that we use the law of reflection to construct the reflected rays. If the reflected rays are extended backward behind the mirror see dashed lines in Figure , they seem to originate from point Q. This is where the image of point P is located. If we repeat this process for point , we obtain its image at point. You should convince yourself by using basic geometry that the image height the distance from Q to is the same as the object height the distance from P to. By forming images of all points of the object, we obtain an upright image of the object behind the mirror.

A plane mirror is a mirror with a flat planar reflective surface. Therefore, the angle of reflection is the angle between the reflected ray and the normal and a collimated beam of light does not spread out after reflection from a plane mirror, except for diffraction effects. A plane mirror makes an image of objects in front of the mirror; these images appear to be behind the plane in which the mirror lies. A straight line drawn from part of an object to the corresponding part of its image makes a right angle with, and is bisected by, the surface of the plane mirror.
