Can humans see virtual images?
Can humans see virtual images? 1 Answer. Virtual image is formed when the diverging rays appear to meet if they are projected backwards. Our eyes have a convex lens which converges light rays. Diverging rays reaching our eye pass through the convex lens and converge on the retina, due to which an image is formed […]
