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.

An object is placed at a distance equal to 2f in front of a convex lens. Draw a labelled ray diagram to show the formation of image. State two characteristics of the image formed.

A lens forms an erect, magnified, and virtual image of an object. (a) Name the kind of lens. (b) Where is the object placed in relation to the lens ? (c) Draw a ray diagram to show the formation of image. (d) Name the device which uses this principle.

A convex lens forms an image of an object equal to the size of the object. (a) Where is the object placed in front of the lens ? (b) Draw a diagram to illustrate it. (c) State two more characteristics of the image.

A lens forms an image between the object and the lens. (a) Name the lens. (b) Draw a ray diagram to shown the formation of such image. (c) State three characteristics of the image.

An object placed 4 cm in front of a converging lens produces a real image 12 cm from the lens. (a) What is the magnification of the image ? (b) What is the focal length of the lens ? (c) Draw a ray diagram to show the formation of image. Mark clearly F and 2F in the diagram.
