(a) Construct ray diagrams to illustrate the formation of a virtual image using (i) a converging lens, and (ii) a perging lens.(b) What is the difference between the two images formed above?

(a)(i) When an object is placed between the focus $F$ and the optic centre $C$ of a converging lens (convex lens), the image formed is virtual, erect, and magnified.

 (a)(ii) When an object is placed anywhere between the optic centre  $C$ and infinity of a diverging lens (concave lens), the image formed is virtual, erect, and diminished. 

(b) The virtual image made by a converging lens (convex lens) is magnified (larger than the object), whereas the virtual image made by a diverging lens (concave lens) is diminished (smaller than the object).
