Step 1
First, we need to identify the diffraction patterns for fcc and bcc crystals in Figure 2. We are given that (a-1, a-2) are for fcc and (b-1, b-2) are for bcc. Show more…

Calculate the $\lambda$ of X-rays which give a diffraction angle $2 \theta=16.80^{\circ}$ for a crystal. (Given interplanar distance $=$ $0.200 \mathrm{~nm} ;$ diffraction $=$ first order; $\sin 8.40^{\circ}=0.1461$ ) (a) $58.4 \mathrm{pm}$ (b) $5.84 \mathrm{pm}$ (c) $584 \mathrm{pm}$ (d) $648 \mathrm{pm}$
The following table lists diffraction angles for the first three peaks (first-order) of the x-ray diffraction pattern for some metal. Monochromatic $\mathrm{x}-\mathrm{ra}-$ diation having a wavelength of $0.0711 \mathrm{~nm}$ was used. (a) Determine whether this metal's crystal structure is $\mathrm{FCC}, \mathrm{BCC}$, or neither $\mathrm{FCC}$ or $\mathrm{BCC}$, and explain the reason for your choice. (b) If the crystal structure is either $\mathrm{BCC}$ or $\mathrm{FCC}$, identify which of the metals in Table $3.1$ gives this diffraction pattern. Justify your decision.
A diffraction grating having 180 lines/mm is illuminated with a light signal containing only two wavelengths, $\lambda_{1}=400 \mathrm{nm}$ and $\lambda_{2}=500 \mathrm{nm}$ . The signal is incident perpendicularly on the grating. (a) What is the angular separation between the second-order maxima of these two wavelengths? (b) What is the smallest angle at which two of the resulting maxima are superimposed? (c) What is the highest order for which maxima for both wave-lengths are present in the diffraction pattern?
