K.C.S.E Physics Q & A - MODEL 2010PP2QN16
(a) Figure 10, shows an object placed in front of a converging lens of focal length 50mm
(i) On the same figure, draw a ray diagram showing the location of the image.
(ii) Use the ray diagram to determine the:
(1) image distance;
(iii) State the adjustment that should be done to obtain a larger virtual image using the same lens.
(iv) State one application of the arrangement in figure 10.
(b) Figure 11, shows a pin 60 mm long placed along the principal axis of the lens used in part (a). The near end of the pin is 80 mm from the lens.
Determine the length of the image.
