Characteristics of image formed in plane 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.

When a ray of light falls on a surface, then it can undergo one of the following three phenomena reflection, refraction, or absorption. When it falls on a normal surface then most of the light gets absorbed. So mirrors are polished surfaces coated with mercury such that they reflect most of the light falling on them. Now based on the type of reflecting surface we can classify mirrors as concave, convex, or plane mirrors. Here we will be talking about the plane mirror only. So to form an image we require at least two rays from the object which meet or appear to meet at a point. In the case of a plane mirror, here we have used three rays for better clarity in the ray diagram shown below.

It is known that when light falls on a smooth and polished surface, like that of a mirror, it undergoes a regular reflection to produce a sharp and clear image of the object lying in front of it. This image is a result of the regular reflection of the light that comes from or reflects from the object and falls on the mirror. In this section, we will be looking at the way the mirrors produce the image of everything lying in front of them by understanding the required concepts. It is the phenomenon of reversal of the mirror image of an object wherein the left side of the object appears to be on the right side of the image and vice versa. This is why when a person standing in front of the mirror raises his left hand, the image in the mirror seems to raise his right hand. Let us take two incident rays, I 1 and I 2 , emerging from the head of an object placed in front of the mirror. I 1 incidents normally whereas I 2 incidents at an angle to the surface of the mirror. After reflection, they give rise to the corresponding reflected rays R 1 and R 2. These reflected rays appear to diverge from a point behind the mirror, where the image of the head of the object is formed. Similarly, if we consider each and every point on the body and draw ray diagrams, we will be able to get the image of the whole body behind the mirror.

While there is an apparent left-right reversal of the orientation of the image, there is no top-bottom vertical reversal. But what if we look at the letters on the transparency?

This is essentially what an image is: A representation of an object formed by reflected or refracted rays of light.

In the case of a plane mirror, here we have used three rays for better clarity in the ray diagram shown below. For the ray starting from point A and travelling in a horizontal direction towards point E, the angle of incidence is 0, and hence it retraces its path. Similarly, the ray starting from A and travelling towards point C follows the law of reflection. When these rays are produced backwards, they appear to meet at a point E.

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. The image formed by a plane mirror is virtual meaning that the light rays do not actually come from the image it is not real image meaning that the light rays do actually come from the image. A virtual image is a copy of an object formed at the location from which the light rays appear to come. Actually, the image formed in the mirror is a perverted image Perversion , there is a misconception among people about having confused with perverted and laterally-inverted image. If a person is reflected in a plane mirror, the image of his right hand appears to be the left hand of the image.

A plane mirror only forms virtual images of real objects. It means if you raise your left hand it would appear in the plane mirror that you have raised your right hand. The size of the image is the same as the size of the object. The distance between the image obtained from the mirror is the same as the distance between the object from the mirror. The image cannot be formed on the screen, i. Your score:. The image is laterally inverted. Read More: Law of Reflection Watch the video and learn more about plane mirrors.

Besides the fact that plane mirror images are virtual, there are several other characteristics that are worth noting. This is why when a person standing in front of the mirror raises his left hand, the image in the mirror seems to raise his right hand. Introduction: Visible Light: Visible light from the Sun comes to Earth as white light traveling through space in the form of waves. Student Extras. Your result is as below. This is a switch of reference frames. If you stand a distance of 2 meters from a plane mirror, you must focus at a location 2 meters behind the mirror in order to view your image.
