Refraction Through a Lens
i) Where should an object be placed so that a real and inverted image of the same size as the object is obtained using a convex lens?
ii) Draw a ray diagram to show the formation of the image as specified in the part a (i).
i) When object is placed at 2F1 (centre of curvature) distance from the optical centre on the principal axis of a convex lens a real and inverted image of the same size of object is formed.
ii) 
An object AB is placed between 2F1 and F1 on the principal axis of a convex lens as shown in the diagram.
The image of the object formed by the lens is given below:
Ranbir claims to have obtained an image twice the size of the object with a concave lens. Is he correct? Give a reason for your answer.
No, Ranbir is not correct.
Using, concave lens only small size upright images are obtained.
An image twice the size of the object with a concave lens cannot be obtained.
A lens forms an erect, magnified and virtual image of an object.
i) Name the lens.
ii) Draw a labeled ray diagram to show the image formation.
i) The lens used here is convex lens.
ii) The labeled diagram for image formation is as shown below:
