16. Determine the expected diffraction angle for the first-order reflection (i.e., n=1) from the (310)set of planes for BCC chromium when monochromatic radiation of wavelength 0.0711 nm is-used. (311) means h=3, k=1, and l=1. Please look at the determination of dnki in the slide set corresponding to Lecture 2. Also note that the diffraction angle means 20. You will determine"0" from the equation, and will have to multiply it by 2.[5 points]
