Question
If lower half of the body of a lens is covered with black paper, the image produced by the lens willdisappear.remain almost unaffected.have its size reduced to half.have its intensity reduced to half.
Solution
If the lower half of the body of a lens is covered with black paper, the image produced by the lens will have its intensity reduced to half. This is because the amount of light that can pass through the lens is reduced by half, but the lens can still focus the remaining light to form an image. The size of the image will not be affected because the lens is still able to bend the light rays that pass through it.
