Q172 / 180 · KCET 2009 · Physics
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
- Afirst decreases and then increases
- Bcontinuously increases
- Ccontinuously decreases
- Correct answerDfirst increases and then decreases
Solution
Beam first converges and then diverges ie intensity of light first increases and then decreases.
Hence, the correct answer is option: 'D'.
