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.

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.

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. 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. The mechanical waves on a rope, waves on the surface of the water, and a slinky are visible to us. So, these mechanical waves can serve as a model to understand the wave phenomenon. Explanation: Types of Waves: Fig:1 Types of waves […]. Introduction: Visible Light: Visible light from the Sun comes to Earth as white light traveling through space in the form of waves.

Of course, this is a little difficult to do when typing from a keyboard.

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. 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.

We only have to look as far as the nearest bathroom to find an example of an image formed by a mirror. Images in flat mirrors are the same size as the object and are located behind the mirror. Like lenses, mirrors can form a variety of images. For example, dental mirrors may produce a magnified image, just as makeup mirrors do. Security mirrors in shops, on the other hand, form images that are smaller than the object. We will use the law of reflection to understand how mirrors form images, and we will find that mirror images are analogous to those formed by lenses. The rays can diverge slightly, and both still get into the eye.

Force: Balanced and Unbalanced Forces Introduction: In a tug of war, the one applying more force wins the game. The angle of incidence refers to the angle between the incident ray and the normal line at the point of incidence. What is the basic principle of image formation by a plane mirror? 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. Your Mobile number and Email id will not be published. Explore the fascinating world of physics with a deep dive into the image formed by a plane mirror. What is the nature of the image formed by a plane mirror? The flatness of a plane mirror ensures consistent reflection of incoming light rays, creating an upright and same-sized image.

A plane mirror is a mirror with a flat planar reflective surface.
