Question 10

          Give three observations in support of de-Broglie’s assumption that moving                          particles behave like waves

  Candidates are expected to reference named particles exhibiting wave property.
  Many candidates got it correct.  Performance was satisfactory.

comments

The expected answers are:

         Particle – wave behaviour
            e.g       -           electrons show diffraction  
                        -           electrons show refraction
                        -           electrons  show reflection
                      -          electrons show interference
                      -          moving electrons  exhibit wave length/frequency
                      -          determination of molecular velocities
