Plane mirror forms which image

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

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.

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 reality, these rays come from the points on the mirror where they are reflected. The image behind the mirror is called a virtual image because it cannot be projected onto a screen—the rays only appear to originate from a common point behind the mirror. If you walk behind the mirror, you cannot see the image, because the rays do not go there. However, in front of the mirror, the rays behave exactly as if they come from behind the mirror, so that is where the virtual image is located. Later in this chapter, we discuss real images; a real image can be projected onto a screen because the rays physically go through the image. You can certainly see both real and virtual images.

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.

Is this a picture of one girl in front of a mirror or is this a picture of twins designed to look like a mirror image? The writing on the shirt is properly mirror reversed, and, as in plane mirror images, the right hand of the object becomes the left hand of the image. The sketch below shows how we see an image in a plane mirror. Plane mirrors work because the light rays create a virtual image behind the mirror. Light rays from the object strike the mirror and reflect according to the law of reflection. When some of the light rays enter our eye, our eye and brain interpret these rays as having traveled in a straight line path. Therefore, our eye and brain track the light rays backward to a position from which they appear to have come. At this position, we see an image. In a plane mirror, the image will be the same size as the object and will be the same distance behind the mirror as the object is in front of the mirror.
