Figure shows the first four peaks of the x-ray diffraction pattern for copper, which has an FCC
Question:
Figure 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 0.1542 nm was used.
(a) Index (i.e., give h, k, and l 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 and compare these with the value presented in Table3.1.
