QUESTION 1 On an X-ray diffractometer, the error in estimating
lattice parameters tends to be suppressed when diffraction peaks at
higher angles are used. Answer the questions below.
(i) Show why the error is suppressed at higher angles by
differentiating Bragg’s law. Include your working.
(2 marks)
(ii) Briefly discuss possible origins of the error in
experiment. (1 mark)
