A parallel beam of light is incident on a converging lens parallel to its principal axis. As one moves away from the lens on the other side of the principal axis, the intensity of light
- A first decreases and then increases
- B continuously increases
- C continuously decreases
- D first increases and then decreases
Answer & Solution
Correct Answer
(D) first increases and then decreases
Step-by-step Solution
Detailed explanation
