The diagram in Figure shows an object AB and a converging lens lens L with foci $F_{1}and{F}_2$.

(a) Draw two rays from the object AB and complete the diagram to locate the position of image CD. Also mark on the Diagram the position of eye from where the image can be viewed.

(b) State three characteristics of the image in relation to the object.

Q.

The diagram in figure shows the position of an object OA in relation to a convergin lens L whose foci are at $F_{1}and{F}_2$.

(i) Draw two rays to locate the position of image.

(ii) State the position of image with reference to the lens.

(iii) Describe three characteristics of the image.

(iv) Describe how the distance of image from the lens and its size change as the object as the object is moved towards $F_1$.

Q.

A converging lens forms the image of an object placed in front of it, beyond $2F_2$ of the lens. (a) Where is the object placed? (b) Draw a ray diagram to show the formation of the image. (c) State three characteristics of the image.

Q. 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.

Q. (a) Draw ray diagrams to show the formation of a three times magnified (i) real image (ii) virtual image, of an object kept in front of a converging lens. Mark the positions of object, F, 2F, O and position of image clearly in the diagram.
(b) An object of size 5 cm is kept at a distance of 25 cm from the optical centre of a converging lens of focal length 10 cm. Calculate the distance of the image from the lens and size of the image.

Q. An object AB is placed between O and $F_1$ on the principal axis of a converging lens as shown in the diagram.
Copy the diagram and by using three standard rays starting from point A, obtain an image of the object AB.
