Bragg's law for x-ray diffraction is 2d sin$\theta$= m$\lambda$, the quantity d is:
A) the height of a unit cell
B) the smallest interatomic distance
C) the distance from detector to sample
D) the distance between planes of atoms
E) the usual calculus symbol for a differential

Question

Quizplus · Accepted Answer

The quantity d in Bragg's law refers to the distance between planes of atoms. This is the distance that causes constructive interference of x-rays when they are diffracted from the crystal lattice. Therefore, option D is the correct choice. Options A, B, and C are not correct as they do not pertain to the crystal lattice or x-ray diffraction. Option E is also not relevant to Bragg's law or x-ray diffraction.
