At a glance:Bragg's law: 2d·sinθ = nλ. Complements braggs-law and diffraction-grating.
Formula
2d·sinθ = nλ.
$$n\lambda = 2d\sin\theta$$$$\lambda = \frac{2d\sin\theta}{n}$$How to Use
- Enter d, order and λ (or angle).
- The tool returns the angle.
Case Studies
d=3.14 Å, n=1, λ=1.54 Å
θ ≈ 14.3°.
FAQ
Glancing angle?
θ is measured from the crystal planes, not the normal.
