Here is the detailed answer for question 49, including the diagram for part (c):
49.
a) The defect of vision shown in the diagram is myopia (nearsightedness).
b) One cause of this defect is:
- The eyeball being too long from front to back.
- The cornea or lens having too much curvature, causing light to focus too strongly.
c) Myopia is corrected by using a concave lens (diverging lens). The concave lens diverges the incoming light rays before they enter the eye, causing them to converge correctly on the retina.
