Figure below shows the first four peaks of the x - ray diffraction pattern for copper, which has a face centered cubic crystal structure: monochromatic X - radiation having a wavelength of 0.1542 nm was used. Reflection indices are presented in the table below. The whole number of wavelengths equals one; (a) Index (t.e., give h, k, and / indices) for each of these peaks. (b) Determine the interplanar spacing for each of the peaks. (c) For each peak, determine the atomic radius for Cu Intensity (relative) 40.0 50.0 80.0 90.0 60.0 70.0 Diffraction angle 20 Crystal Structure BCC Reflections Present (h + k + I) even Reflection Indices for First Sir Planes 110, 2010), 211, 220, 310, 222 111 200, 220, 311, 222, 400 100, 110, 111, 200, 210, 211 FCC h, k, and I either all odd or all even Simple cubic All
