A convex lens forms a real image of a point object placed on its principal axis. If the upper half of the lens is painted black, then
- A the image shifts upward
- B the image shifts downward
- C the intensity of the image decreases
- D the intensity of the image increases
Answer & Solution
Correct Answer
(D) the intensity of the image increases
Step-by-step Solution
Detailed explanation
When a upper part of lens is covered then there will be no shift in the image but the intensity of image decrease due to less number of light rays forming the image.
