A parallel beam of light travelling in air is incident on a glass lens. The beam is perpendicular to the lens as shown in Fig. 8.1. The dashed line P indicates the position of the lens. The centre of the lens is dot C.

1. (a)(i)indicate the shape of the lens by drawing the outline of the lens around dashed line P[1]
2. (a)(ii)draw the path taken by each ray of light after it passes through the lens.[2]
3. (b)(i)Fig. 8.2 is a simplified diagram of a short-sighted eye. Light from a distant object strikes the eye lens and enters the eye. On Fig. 8.2, continue the three rays in the eye until they reach the back of the eye.[2]
4. (b)(ii)State how the image of a distant object detected by a normal eye differs from the image detected by the short-sighted eye.[1]
5. (b)(iii)Explain how a diverging lens corrects the sight of a short-sighted eye viewing a distant object.[1]
6. (c)(i)Fig. 8.3 is a full-scale diagram drawn on a grid, on which the dashed line L represents the lens and the arrow O the object. By drawing on Fig. 8.3, find the position of the image I of object O. Draw image I and label it I.[4]
7. (c)(ii)Explain whether the image produced is real or virtual.[1]
8. (c)(iii)On the grid in Fig. 8.3, write an E in a position from which an eye can see the image.[1]
9. (c)(iv)Determine the linear magnification produced.[2]
