Describe with the help of a ray-diagram, the formation of image of a finite object placed in front of a convex lens between f and 2f. Give two characteristics of the image so formed.
The ray-diagram shows the formation of the image of a finite object that is placed in front of a convex lens and between $f$ and $2f$:
Two characteristics of the image so formed are:
1. Real and inverted.
2. Magnified.
Explanation
When an object is placed between $F'$ and $2F'$, means the object is at a distance greater than the focal length $f$ and less than twice the focal length $2f$, then the image formed is real, inverted, larger than the object (or magnified), and beyond the $2F$ on the other side of the lens.
