(a)[1]
Draw a cross-section of a diverging lens.
(b(i))[1]
Using Fig. 5.1, determine the lens focal length.
(b(ii))[1]
On Fig. 5.1, place a vertical arrow of height 2.1 cm at a distance of 3.0 cm from the centre of the lens, and label the arrow O. This arrow represents the object.
(b(iii))[3]
On Fig. 5.1, use two rays from the tip of the object arrow to locate the tip of the image. Then draw a further arrow to represent the image.
(b(iv))[2]
Using the image marked on Fig. 5.1 in (b)(iii), determine the linear magnification obtained.
(b(v))[1]
Explain whether the object's image is real or virtual.
