Difference between Real Image and Virtual Image

Difference between Real Image and Virtual Image

There are two types of images which are formed by lenses which are as follows real image and virtual image. And there are many types of lenses which are biconvex lens, Plano convex, converging lens, diverging lens, Plano concave and biconcave lens. And the formation of image is different for different lenses.

 

Real Image

Real image is formed by convex lens which is also known as converging lens. The convex lens converge the rays of light and a real image is formed. Convex lens has thick middle and thinner edges. And the point of formation of lens is called principal focus.

Virtual Image

Virtual image is formed by concave lens which is called diverging lens. This image is formed when rays of light diverge from lens. Concave lens are thick at the edges and thinner at the middle.

Real Image VS Virtual Image

 

Formation:

Real images are formed by convex lens which converge the rays of light and image is formed.

Concave lens form Virtual Image and the rays do not intersect each other in contrary it is formed by diverging the rays of light.

Real images are used in digital camera and projectors so it has vast use.

Virtual images are also formed in the mirror as the rays of light do not actually permit through the image
