what efffect will on the image if convex lens is half shaded(black) ?

Answer» Hopefully you should understand....bit I\'m telling you its hard to explain without the ray diagram and also it is a very...imp ques..
The image won\'t be affected , just because there are not only one or two rays that fall on the lens there is whole beam of light and that\'s why image will be formed where it should
