How a complete image formation possible when a convex lens is half covered with a black paper?
Asked by | 21 Mar, 2008, 07:35: PM
answered-by-expert Expert Answer

When the convex lens is half covered it still forms a real and inverted complete image but its intensity decreases  because after refraction number of rays decreases, hence intensity decreases.
