Figure 34.21 shows diffracted \(\mathrm{x}\)-ray intensity as a function of the Bragg angle \(\alpha\), obtained using \(\mathrm{x}\) rays having a wavelength of \(0.11 \mathrm{~nm}\).

(a) Without calculating values for the lattice spacing \(d\), identify which of the two peaks corresponds to a greater distance between adjacent planes in the sample being studied.

(b) Calculate the distance between adjacent planes corresponding to each peak.
