You are given a convex lens of focal length $10\, cm$. Where would you place an object to get a real,inverted and highly enlarged image of the object? Draw a ray diagram.

(N/A) When an object is placed at the principal focus $(F)$ of a convex lens,the refracted rays become parallel to each other and meet at infinity. This results in the formation of a real,inverted,and highly enlarged image at infinity.
Therefore,the object should be placed at a distance of $10\, cm$ from the optical centre of the lens.
The ray diagram is as shown below.
