Assume that a Bragg peak is observed at 20 = 30.12" when a strictly monochromatic Cr Ko radiation is employed. Using information about the characteristic wavelengths found in Volume C of the International Tables for Crystallography (https://it.iucr.org/) a. Determine the Bragg angle of the same Bragg reflection for Cr Koz radiation - 7 points b. Now assume that a Bragg peak is observed at 20 = 30.12" when a strictly monochromatic Mo Ko radiation is employed, and determine the Bragg angle of the same Bragg reflection for Mo Koz radiation - 3 points
