An illuminated object is placed at a distance of 20 cm from a converging lens of focal length 15 cm. The image obtained on the screen is:(a) upright and magnified (b) inverted and magnified(c) inverted and diminished (d) upright and diminished
(b) Inverted and magnified
Explanation
When an illuminated object is placed at a distance of 20 cm from a converging lens of focal length 15 cm, then it means the object is between $f$ and $2f$ $(2f=30 cm)$.
For an object placed between the focal length $f$ and twice the focal length $2f$ of a converging lens, the image formed is real, inverted, and magnified.
