Two planes of a crystal are separated by 3.25 Angstroms (or 3.25 $\times$ 10^-10 m). How many maxima will there be in the diffraction pattern of 2.0 Angstrom X-rays from this crystal? A) 4 B) 2 C) 3 D) an infinite number E) 1

Question

Quizplus · Accepted Answer

The condition for maxima in a diffraction pattern is given by Bragg's law: nλ = 2d sin(θ). For maximum n, λ = 2.0 Å and d = 3.25 Å, n must be an integer. The maximum n is 3, as nλ ≤ 2d.
