A convex lens forms a full image of the object on a screen. If half of the lens is covered with an opaque object, then :

Options

  1. Athe image disappears
  2. Bhalf of the image is seen
  3. Cfull image is seen and of same intensity
  4. Dfull image is seen and of decreased intensity

Correct answer

D. full image is seen and of decreased intensity

Step-by-step solution

If half of the lens is covered with an opaque object, then, full image is seen but intensity of image decreases.
