Characteristics of image formed in plane mirror

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.

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 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. If you raise your right hand, the image raises what would seem to be its left hand. This is often termed left-right reversal.

To clarify, when we say that the distance between the man and his image is 1 metre, we are referring to the distance between the man and the mirror itself.

In the case of a plane mirror, here we have used three rays for better clarity in the ray diagram shown below.

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.

Everything you need to know on. In reality, all reflected rays appear to originate from a common point behind the mirror, creating a 'virtual' image. What is the basic principle of image formation by a plane mirror? Force: Balanced and Unbalanced Forces Introduction: In a tug of war, the one applying more force wins the game. The underlying principle involves light and optics. Already have an account? Scattering Of Light Definition. Understanding the Physics of Image Formation by Plane Mirror Let's dive into the interesting subject of image formation by plane mirrors. If you stand on your feet in front of a plane mirror, the image does not stand on its head. Lateral inversion: 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. You might have noticed that emergency vehicles such as ambulances are often labeled on the front hood with reversed lettering e. The image formed by a plane mirror is known as a virtual image. The image is virtual, the image distance equals the object distance, the image size is the same as the object size, the image is laterally inverted and upright. Deepa May 22, at pm. A perfect summary so you can easily remember everything.

We only have to look as far as the nearest bathroom to find an example of an image formed by a mirror.

How does the orientation of an image formed by a plane mirror compare to the actual object? In one second, the toddler has moved towards the mirror by a distance of 0. 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.

The distance between the image obtained from the mirror is the same as the distance between the object from the mirror. A plane mirror plays a crucial role in various everyday applications like the mirrors used in bathrooms and bedrooms and rear-view and side mirrors in cars, as well as scientific and technological applications like in dental mirrors, optical benches, periscopes, holography, telescopes, microscopes, laser technology, and teleprompters. Nie wieder prokastinieren mit unseren Lernerinnerungen. A virtual image is a special type of image that can only be seen by using specific optical tools. It gives the illusion that light is coming from a point in space behind the mirror, even though it's actually reflected off the mirror's surface. The light rays from you strike the water and reflect, seeming to come from a point beneath the water surface — thus, forming your 'virtual' image.
