On the other hand, when light rays originating from one side of the lens are refracted by the lens so that they diverge on the other side of the lens, a virtual image is formed. Virtual images appear to be on the lens or the mirror itself. A normal eye can take these divergent rays and converge them to points on its retina. Wiring a reliable temperature switched outlet, Generalization of any() function with switchable default parameter for empty iterables. But in the case of a virtual image, there are no actual light rays coming together at the location of the virtual image which is why one cannot see a virtual image on screen. Real objects are points from which light diverges. Thank you for your answer. In a real image, light rays are brought to a focus at the position of the image.

This is why it is called a virtual image.

But suppose you place the pupil of your eye at S2 (where that blue thing is in the top right hand diagram). An illuminated object is placed at the 0.0 cm mark on a metre rule, a converging lens of focal length 10.0 cm at the 15.0 cm mark, and another such lens at the 25.0 cm mark. How is it possible that a converging lens can form a virtual image if its function is to make the light converges? The best example of a real image is the one formed on a cinema screen.
