Observation

This was another popular question among the candidates.  While majority had no problem tackling part (a) some candidates could not satisfactorily answer part (b).  Performance was fair.
The expected answer are:
(a)        Particles used in explaining the wave nature of matter                                                         
                       e.g.  -  Hydrogen atom/proton
                              -   Helium atom
                              -    Helium nuclei/alpha particles
                              -    Electrons
                              -    Neutrons                     
(b)        One  device whose invention is based on wave  nature of matter
             
            e.g.   -   Electron microscope
                     -   Scanning tunneling microscope (STM)
