Question

Q4) The figure below shows the first five peaks of the x-ray diffraction pattern for tungsten (W), which has a BCC crystal structure; monochromatic x-radiation having a wavelength of 0.1542 nm was used. (a) Index (i.e., give h, k, and l indices) for each of these peaks [3 marks]. (b) Determine the interplanar spacing for one of the peaks [3 marks]. (c) Using any peak peak, determine the atomic radius for W [2 marks] Intensity 0.0 20.0 40.0 60.0 80.0 100.0 Diffraction angle 2$\theta$
