The position, nature and size of the image of an object formed by a thin convex lens can be studied, using new cartesian sign convention and drawing ray diagrams. The position, nature and size of the image formed depend on the position of the object with respect to the optical centre of the convex lens.

The ray diagrams below summarise the formation of images of an object AB formed by a thin convex lens when the object is placed at various positions.

Physics Practical Class

The nature, position, and size of the image can be noted and measured from the optical centre O of the thin convex lens.
