Did we solve your problem today?

Bragg's law explains how crystals diffract X-rays, the basis of crystallography.

The math behind it

n·λ = 2d·sinθ. Constructive interference occurs at specific angles set by the lattice spacing d.

λ = 0.154 nm, d = 0.282 nm, n = 1 → θ ≈ 15.86°.

What if sinθ > 1?

No diffraction of that order is possible for those values.
