K.C.S.E Physics Q & A - MODEL 2014PP2QN018

​Figure 11 shows an object placed 10cm infront of a concave mirror whose radius of curvature is 40 cm.

​(a) (i) On the same figure, draw a ray diagram to show the position of the image formed. 
(ii) Use the ray diagram to determine:
(I) the image distance. 
(II) the magnification. 
(iii) State where the position of the image would be if the object had been placed at the principal focus. 
(b) Draw a ray diagram to show the formation of a partially dark shadow and a totally dark shadow during the eclipse of the sun.
