Fig. 4.1 is an unfinished ray diagram showing object O, a converging lens and the principal axis. The focal points of the lens are both labelled F.
Fig. 4.1 shows a converging lens with object O on the left of the principal axis. Rays leave the object and are refracted by the lens. The focal points on either side are labelled F.
(a(i))[3]
Complete the ray diagram to show the image produced by the lens. Label your image I.
(a(ii))[3]
Circle three descriptions from the list that apply to the image formed in (i).
diminished
enlarged
inverted
same size
real
upright
virtual
(b(i))[1]
State the name of the vision defect that can be corrected by a converging lens.
(b(ii))[2]
Describe how a converging lens corrects the defect in (i). A ray diagram may help.
