1The ray diagram shows the image of an object formed by a converging lens.
What is the focal length of the lens?
- AA 40 cm
- BB 50 cm
- CC 72 cm

7Which statement about a converging lens is not correct?
- AA A ray parallel to the principal axis of the lens is refracted through the principal focus.
- BB All rays of light refracted by the lens pass through the principal focus.
- CC The distance between the centre of the lens and the principal focus is the focal length.
- DD The principal focus of the lens is a point on the principal axis.
8An object is placed in front of a converging lens. The lens has a focal length f.

Which of the rays are drawn correctly?
- AA ray Y only
- BB ray Z only
- CC ray X and ray Y
- DD ray X and ray Z
12A converging lens in a projector is used to make an enlarged image of a small piece of film on a screen.
At which labelled point could the piece of film be placed so that the lens produces this image?
- AA
- BB
- CC
- DD
13 A thin converging lens is used to produce, on a screen, a focused image of a candle.
- AA The image is at the principal focus (focal point) of the lens.
- BB The image is bigger than the object.
- CC The image is closer to the lens than the object is.
- DD The image is inverted.
14 The diagram shows a converging lens forming an image of an object.
Which statement about the image is correct?

- AA
- BB
- CC
- DD
- AA
16An object O is placed close to a thin converging lens.
