Q15

* Your answer is incorrect. Figure below shows the first four peaks of the x-ray diffraction pattern for copper, which has an FCC crystal structure; monochromatic x-radiation having a wavelength of 0.1542nm was used. (a) index (i.e. give h, k, and lindices) for each of these peaks. Peak 1 Peak 4: (b) Determine the interplanar spacing for each of the peaks. (b) Determine the interplanar spacing for each of the peaks. Peak 1: Peak 2 Peak 3: nm Peak 4: nm (c) For each peak, determine the atomic radius for Cu and compare these with the value presented in Table Atomic Radii and Crystal Structures for 16 Metals
