Draw ray diagrams to show the formation of three times magnified (a) real, and (b) virtual image of an object by a converging lens. Mark the positions of O, F and 2F in each diagram.

Answer:

(a) For real image: To get three times magnified image, the object is placed between \[{{F}_{1}}\] & \[2{{F}_{1}}\]

(b) For virtual image: To get three times magnified image, the object is placed between the \[{{F}_{1}}\], and optical centre O.
