Fig. 6.1 illustrates the route taken by a ray of visible light starting at the top of an object and passing through a converging lens. The diagram also shows line XY and a scale, with each square standing for 1 cm.
(a)[1]
State what line XY stands for.
(b)[1]
Determine the focal length for the converging lens.
(c)[2]
On Fig. 6.1, draw a second ray from the object. Carry the ray through the lens until it intersects the ray shown in Fig. 6.1.
(d)[2]
On Fig. 6.1, draw an arrow to show the image. Label it 'image'.
