ICSE Class 10 Answered
a virtual image cannot be focused on a screen . Yet when we see a virtual image,we obviously bring it to the screen that is the retina of our eyes. is this a contradiction?

Hi Siddhi,
No it is not a contradiction.
If you understand and visualize carefully then you can only see a virtual image from your eye if you are directly behind the lens or the mirror.
Suppose a convex lens is forming a virtual image, then you will not be able to project that image. But, if you stand directly behind the lens then the light passing through lens meets your eye and forms a real image on the retina.
So, you get a feeling that you are seeing a virtual image or projecting a virtual image on the screen/retina.
However, this is not the case.
