Answer:When you cover half the lens you get a fainter image. Effectively you are cutting out half the light rays, but they still produce an entire image. In the diagram below you can see that rays from the top and bottom of the tree still pass through the top half of the lens to form.
Yes it will. Even if half of the convex lens is covered with black paper, the lens will produce a complete image. however the intensity of the image may be less. It can be observed experimentally by using a lighted candle and a convex lens.
