In an X-ray diffraction experiment a thorium (Th) sample is irradiated with tungsten (W) rays La

a) Calculate La

b) Thorium crystallizes in FCC and its density is 11.72 g/cc. Calculate the lattice constant a.

c) In the diffraction diagram calculate the angle of the fourth reflection

d) If we had radiation with neutrons what would their speed be so that we would have reflections at the same angles as X-rays (Sub: remember deBroglie's law and take a neutron mass equal to proton)
