Difference Between Real Image and Virtual Image

Difference Between Real Image and Virtual Image

A real image and a virtual image are different forms of image. The main difference between real and virtual images lies in the way in which they are produced. A real image is formed when rays converge, whereas a virtual image occurs where rays only appear to diverge. Let us look at more differences between real images and virtual images in this article.

Difference Between Real Image and Virtual Image

To obtain a real image the light source and the screen must be placed on the same plane. The image is obtained by using a converging lens or a concave mirror. The size of the image depends upon the placement of the object.

The virtual image, on the other hand, is an upright image that can be achieved where the rays seem to diverge but do not converge in reality. This image can be produced with the help of a diverging lens or a convex mirror.

 

Difference Between Real Image and Virtual Image
Real Image Virtual Image
Real images are inverted Virtual images are erect
Convex lenses form a real image  Concave lenses form a virtual image
Real images are formed on the screen Virtual images appear to be on the lens or the mirror itself
Real images are formed by a concave mirror Plane, convex mirror and concave lens forms a virtual image
Real images are formed due to the actual intersection of light rays Virtual images are formed due to the imaginary intersection of light rays

Therefore, we can say that the difference between real and virtual images is that the real image can be obtained on the screen whereas the virtual image cannot be obtained on the screen.

  1. Best platform for learning.

  2. If we make the image by extending the rays backward then how we see the image. As it is not really forming an image. By doing extentions mathematically we can make more images of objects which will not make an unique image of the object

    1. When the rays are extended backwards, the image obtained is known as the virtual image. The virtual image cannot be obtained on the screen. Also, the characteristics of the virtual image are the opposite of the real image.

  3. This app is very good for learning at home . It is very useful for me . Thank you Byjus
