In part (a) almost all candidates that attempted the definition got it wrong; However, many candidates were able to list the three types of eclipse correctly.
In part (b) (i) & (ii), performance was above average. In part (iii) performance was fair.  Some   candidates however have problems converting to metres and also the stating the correct unit of power of a lens.
In part (c), candidates are expected to make use of the concept of echo where V =  .  However performance was low because of lack of comprehension of the question
In part (d) Performance  was fair.

The expected answers are:

(a)(i)   An eclipse is a shadow resulting from the obstruction of light from the sun by either
  the moon or the earth.
     (ii)   -    Solar eclipse (eclipse of the sun)
   -    Lunar eclipse(eclipse of the moon)
   -    Annular eclipse

(b)(i)   The eye defect
   Long sight (hypermetropia)/hyperopia
    (ii)   The type of lens
  Convex/converging lens

   (iii)    Power of lens
   Power  =  1/f

   =    

   =      +  10 dioptre (D)

(c)    V  = 

         d  =  
                    
             =   

                     =    0.952m
      
        (d)       M =                         

                  0.6  =                     =

                   u  =  15 cm                    = 

                                          f  =  -22.5cm
