How will the image formed by a convex lens be affected if the central portion of lens is wrapped in black paper ?

 answer: The full image will be formed, but it is less bright


As a result of a huge number of rays from the object forming an image. As a result, if any part of the lens is obscured, an image will appear. When compared to an image created without covering the lens, the brightness of the image will be lowered. The whole image will be generated if the centrepiece of the lens is wrapped in black paper, although it will be less bright.
