Draw a ray diagram to show the formation of the image of an object placed between the optical centre and focus of a convex lens. Deduce the relationship between object distance, image disatnce and focal length of lens.

An object is placed in between the optical centre and focus of a thin convex lens. What is the nature of image of the object?

Draw a ray diagram in each of the following cases to show the formation of image, when the object is placed : between optical centre and principal focus of a convex lens.

Draw a ray diagram to show how the image is formed when the object is placed between f and 2 f distances from a convex lens.Deduce the relation between the distances of he oject and the image from the lens and the focal length of the lens under this condition.

Draw a ray diagram to show the image formed by a convex lens when the object is placed between F and 2F.
