A lens is made up of 3 different transparent media as shown in figure. A point object $O$ is placed on its axis beyond $2 f$. How many real images will be obtained on the other side?
No image will be formed
$3$
$2$
$1$
Solution
Since all three medium will form individual real images at different points on the other side of lens (as object distance is more than $2 f$ )
$\therefore$ Number of real images formed $=3$.
