संक्षेप में उत्तर
उत्तर
It is a convex lens. If we keep on decreasing the distance between the object and the tens, the size of the image increases. But when an object comes between principal focus and lens then a magnified, virtual and upright image is formed. So, we will not be able to obtain the image on the screen as it will be a virtual image.
